LWN.net Weekly Edition for October 30, 2003

Happenings on the DMCA front

It has been a busy week for those who watch the Digital Millennium Copyright Act and its effects. Here's a quick summary of what has been happening.

Every three years, the Librarian of Congress must consider applications for exemptions to the DMCA's anti-circumvention provisions. The decisions for this cycle have just been posted; they may be downloaded in PDF format. Four applications were granted this time:

1. Compilations consisting of lists of Internet locations blocked by commercially marketed filtering software applications... Interestingly, the exemption explicitly does not extend to anti-spam blacklists.

2. Computer programs protected by dongles that prevent access due to malfunction or damage and which are obsolete.

3. Computer programs and video games distributed in formats that have become obsolete and which require the original media or hardware as a condition of access.

4. Literary works distributed in ebook format when all existing ebook editions of the work ... contain access controls that prevent the enabling of the ebook's read-aloud function and that prevent the enabling of screen readers to render the text into a specialized format.

Many other proposals were turned down. As Ed Felten notes, "My own exemption request, asking for exemptions for information security researchers, was denied as expected." Blanket exemptions for (otherwise) non-infringing uses, or for fair use were turned down as not properly specifying which works should be exempted. A requested exemption for making backup copies of DVDs went down because it did not show, to the Librarian's satisfaction, that DVDs are fragile or that making a backup copy is a noninfringing use.

Static Control Components has been engaged in a DMCA fight with Lexmark over printer cartridges. SCC makes toner cartridges which work in Lexmark's printers; Lexmark has made the claim that SCC's products, by circumventing a printer "feature" that causes it to not function with cartridges manufactured by others, violate the DMCA. As part of its fight, SCC asked for an exemption specific to printers that would make its products unambiguously legal. The proposed exemption was turned down because, according to the Librarian, the existing interoperability exemption covers this case. Thus, in losing its exemption, SCC appears to have won its case with Lexmark; the company lost no time in issuing a press release to that effect.

Speaking of press releases, 321 Studios, a company which sells a DVD-copying program, has announced that it will be appealing the ruling on the making of backup copies of DVDs.

Finally, there is a growing case involving numerous people - mostly college students in the U.S. - who are fighting DMCA takedown notices from Diebold Election Systems. Diebold is a manufacturer of computerized voting machines. These students came into possession of some internal Diebold correspondence which shows a distressingly cavalier attitude toward the accuracy of election votes and the integrity of the election process in general. Diebold, rather than facing up to its problems, is simply trying to suppress the incriminating memos. For those who understand the net, the results of this effort have been entirely predictable: copies of the correspondence have now been distributed worldwide. The organizers of this effort are calling for help, however, in the form of additional mirrors and publicity. This effort deserves support; transparent and accurate management of elections is too important to be pushed aside by the DMCA.

A look at Fedora Core 1

With the first stable release of the Fedora Core scheduled for early next week, we thought we'd take a look at the final test release to see what users could expect from Fedora.

This release ("Severn") looks and feels like recent Red Hat releases, which is not entirely surprising. The default desktop is still GNOME with Metacity as the window manager. For the most part, if you're familiar with the Red Hat 9 release, Fedora will contain few surprises. The installation procedure is mostly the same as Red Hat 9, though users now have a few additional install options. Fedora 0.95 includes the ability to perform a graphical install via FTP, HTTP and the ability to perform an install via VNC.

We installed the Severn release on two machines to see how well it fared. On one machine we installed the "Server" package set, and performed a "Custom" install on the second machine. The entire install took less than thirty minutes on an Athlon 2600+ XP machine with 1 GB of RAM, and about forty-five minutes on an Athlon 1GHz machine with 1 GB of RAM.

The only real glitch we encountered was that Severn had a little trouble setting up the Matrox G450 dual-head video card. Though it offered the option of performing a dual-head setup that spanned both monitors, it kept producing a cloned display. A quick hand-edit of our XF86Config file solved the problem.

The firewall configuration during installation is somewhat simpler than the configuration that was present in Red Hat 9. Red Hat 9 offered "High," "Medium," and "No Firewall." The option with Fedora is to turn the firewall on or off. The user is also able to specify specific ports that should be passed through the firewall. The installer offers the options of passing through SSH, HTTP, FTP, Telnet, SMTP or specifying their own protocol that can be passed through.

Though it's a small thing, one also notices a difference in attitude during the installation. Instead of seeing Red Hat promotions during the install, the user is told that Fedora has a new graphical boot feature ("Who understood all that text scrolling by anyway?") and is encouraged to sign up for Fedora user and developer lists ("Hey! It's better than spam!").

There is a full list of packages for Severn test 3 release here. It may change slightly for the final release. Most of the packages have been updated since Red Hat 9, of course, but the package list hasn't changed that much.

One new inclusion in Fedora is Yum, an APT-like package installer/updater. Yum is not installed by default, but it is included on the Severn CDs. Yum has a command set similar to apt-get. One striking difference, however, is when using "yum check-update" to retrieve information on changed packages. The apt-get update command simply retrieves an index file for each package repository, which is fairly fast. Yum, on the other hand, retrieves RPM header information for every installed RPM, which can be very time-consuming.

Some packages have not made the cut from Red Hat 9 to Fedora. The LPRng print system is no longer supported or included with Fedora. CUPS is now the official, and only, print spooler for Red Hat/Fedora systems. According to the Fedora 0.95 release notes, LPRng will be replaced by CUPS even if the user decides to upgrade an existing Red Hat system with Fedora. Galeon is out, replaced by Epiphany. Users no longer have the option of using the LILO bootloader. Pine has been kicked due to licensing issues and "long-term maintenance concerns." Zebra has been replaced by the Quagga Routing Suite, and Tripwire has been removed as well.

Another interesting change is the inclusion of the Native POSIX Thread Library (NPTL). The Severn release ships with a 2.4.22 kernel with NPTL replacing the user-space LinuxThreads implementation. This means that some applications, notably Sun's Java Runtime Environment (JRE) prior to 1.4.1 and IBM's JRE will have issues. For applications that need the old implementation, there is a workaround described in the release notes.

The Fedora kernel also includes "exec shield," a kernel patch that we covered last May. By default exec shield is turned on for programs that are "marked" for this functionality. For the Fedora release, this pretty much means that the program needs to have been built with the Fedora toolchain.

Fedora Core 1 is still very much a Red Hat product, even if the "Red Hat Linux" name has been filed off. There has not, as yet, been time for a true development community to form; traffic on the Fedora mailing lists is tiny relative to those of, say, Debian or Mandrake's Cooker. So it is hard to guess what Fedora will look like in the future. But, if Fedora 0.95 is any indication, the first "stable" release looks to be shaping up well. If all goes as planned, Fedora Core 1.0 will be released on Monday, November 3.

SCO responds to IBM's counterclaims

The SCO Group has filed its response to IBM's counterclaims; the full text may be found in PDF format. Since this document is structured as a set of direct responses to the claims made by IBM, much of what's there must be read in the context of IBM's amended filing to make sense. SCO's responses come down to a relatively small set of points, however, which we will examine here.

One area of dispute has to do with exactly what rights were bought from Novell in 1995. Novell claims the right to veto some of SCO's actions, such as the yanking of IBM's AIX license. SCO disputes that claim. Without access to the actual agreement between the two companies, it is impossible to come to any conclusion here; this will be a job for the court.

IBM's claim #16 reads:

This would seem like a relatively uncontroversial thing for IBM to say. Even SCO, in the end, has embarked on all this litigation because Linux has become "the operating system of choice" for many of its former customers. Here's SCO's response, however:

This is, of course, the company that made a go at developing and selling Linux for years, even after it obtained its rights, whatever they may be to the Unix code base.

Much of SCO's response, however, is aimed in a different direction: SCO is, once again, claiming that the GPL is not an enforceable license. Thus, for example, when IBM claims:

SCO responds with:

In other words, according to SCO, those who write code are not entitled to attach a license to it, and even if they were, the GPL is not a valid license. This anti-GPL rhetoric reaches its peak in the "affirmative defenses" at the end of the filing:

The counterclaims offer no evidence for any of the above claims; they are simply put out there to stand on their own. The first claim will, eventually, depend on what a court finds, but many are confident that the GPL will hold up just fine. The second is ridiculous; whether or not the FSF is selective in its enforcement of the GPL has no relevance to how IBM enforces its own copyright rights. Bringing the Constitution and antitrust law into it (with the third claim) is new, but SCO's previous reasoning on the GPL and copyright law has been humorous at best.

In other details, SCO denies that its "letter to Linux users" threatened any sort of litigation. Strangely enough, SCO has removed that letter from its web site, making it harder for anybody who might want to check for themselves. Happily, this SCO v. IBM site has kept a copy handy.

SCO also goes to some lengths to try to fight off IBM's patent claims. The response even alleges that IBM might not own the patents at all.

Most of the defenses seem like a sideshow, however, compared to SCO's sustained attacks on the GPL. Clearly, the company sees the GPL as an obstacle that must be overcome. Just why SCO is so eager to see the GPL defeated is still not entirely clear, however. Perhaps the company simply wishes to destroy the Linux ecology outright so that there might yet be room for its outmoded, failing proprietary offerings. Or perhaps SCO is trying to find a way that it can apply a tax to all Linux shipments. Or maybe it is all a simply set of delay and FUD tactics while the real goal is pursued elsewhere. Given that we are facing a concerted attack on one of the pillars of the free software community - an attack now funded with another $50 million in investment money - it is proper to be concerned. Unless the attackers can come up with some better arguments, however, the GPL looks set to stand for a long time yet.

Weblog Comments - A New Frontier for Spam

The war over spam has erupted recently in a new arena: weblog comments. The parallels to the battles that have been fought on the email spam front are considerable, but unlike email spam, weblog spam is targeted at Google (and other search engines that use number of links to derive page rankings) to increase the visibility of the sites that are being advertised via spam. Comment spam seems to be on the rise with weblog owners noticing a large increase in the number of incidents over the last month or two.

Weblogs are sites that allow the owner to post articles and essays of whatever happens to strike their fancy that day and most weblog software enables readers to post comments on the stories. LWN's comment system provides the same feature for this site but, unlike LWN comments, many weblogs allow (and even encourage) anonymous comments. That openness, like the lack of sender authentication for email, provides an avenue for abuse. Requiring registration before allowing comments does not eliminate the problem entirely (LWN has had a small amount of comment spam), but it does increase the amount of work the spammer must do.

The basic mode of attack uses a program to automatically post comments on multiple articles throughout the weblog. These unwanted messages include the URL of a website that will give you the opportunity to buy one or more of the usual items: diplomas, prescription drugs, porn, etc. The program then moves on to other sites using the same software, aided, no doubt, by the various directories of weblogs using a particular software package that are available. Eventually, Google and other search engines visit the weblog sites; thereafter, the spammer's site gains a high ranking due to all of the links to it that are found.

One of the more popular (though not entirely free) packages for running a weblog is Movable Type; its user community has been the most active so far in combating comment spam. For example, one set of tips (described by Yoz Grahame) attempts to thwart the way the current spam programs work by changing the default behavior of the software. Something as simple as changing the "post a comment" link can be sufficient to confuse most automated comment posting scripts. These techniques will only help until enough people implement them and it makes it worth the effort for a spammer to write more adaptable code to circumvent them.

Many of the other comment spam handling techniques will seem very familiar to anyone who has been dealing with the deluge of email spam: bayesian filtering and blacklisting based on the URLs in the comment and/or user profile are two of the more popular techniques. Bayesian filtering uses the frequency of words in a message and a database of word counts from previous messages that have been categorized as spam or non-spam (often called "ham") to determine a probability that the new message is spam. If the probability is too high, the message is rejected. The blacklisting patch collects the URLs that are advertised in the offending messages and rejects any comments that refer to any of those URLs. Both of these techniques can be worked around by a spammer with enough incentive, but it does make it much more difficult.

Another technique that is becoming more popular is email and web-based challenge-response systems which generate a blurry graphic that is (presumably) only readable by humans. Such systems require that the text in the graphic be typed into a form to ensure that a human, and not a program, is initiating the action. This technique, too, has made its way into the arsenal of webloggers via this plug-in for Movable Type. This scheme does have a number of downsides because it requires a graphical browser to post messages and may be unusable by the visually impaired.

Other weblogging software developers may have run into this problem and come up with their own sets of fixes, but the Movable Type community appears to be the at the forefront of this particular battle. Perhaps the spammers have yet to target other systems in an automated way. If (or more likely when) they do, newly targeted weblogging software can use one or more of the techniques above to combat the spam.

Both weblog comment and email spam fighters are running into the same issues and producing similar solutions in many cases and cooperation between the two groups will lead to better spam fighting. One of the future plans for Jay Allen's blacklist (above) is to create a distributed list of URLs that are being advertised via spam and with proper controls one can imagine that list being useful to the email spam fighting crowd. A filter using the rules for email message bodies in SpamAssassin might be useful for folks confronting spam in their weblog comments as well.

kernel-utils: setuid vulnerability

Package(s):	kernel-utils	CVE #(s):	CAN-2003-0019
Created:	February 7, 2003	Updated:	January 21, 2005
Description:	The kernel-utils package contains several utilities that can be used to control the kernel or machine hardware. In Red Hat Linux 8.0 this package contains user mode linux (UML) utilities. The uml_net utility in kernel-utils packages with Red Hat Linux 8.0 was incorrectly shipped setuid root. This could allow local users to control certain network interfaces, add and remove arp entries and routes, and put interfaces in and out of promiscuous mode. All users of the kernel-utils package should update to these packages that contain a version of uml_net that is not setuid root. Alternatively, as a work-around to this vulnerability issue the following command as root: chmod -s /usr/bin/uml_net

sane-backends: several vulnerabilities

Created:	September 11, 2003	Updated:	February 20, 2004
Description:	Alexander Hvostov, Julien Blache and Aurelien Jarno discovered several security-related problems in the sane-backends package, which contains an API library for scanners including a scanning daemon (in the package libsane) that can be remotely exploited. These problems allow a remote attacker to cause a segfault fault and/or consume arbitrary amounts of memory. The attack is successful, even if the attacker's computer isn't listed in saned.conf. You are only vulnerable if you actually run saned e.g. in xinetd or inetd. If the entries in the configuration file of xinetd or inetd respectively are commented out or do not exist, you are safe. Try "telnet localhost 6566" on the server that may run saned. If you get "connection refused" saned is not running and you are safe. The Common Vulnerabilities and Exposures project identifies the following problems: CAN-2003-0773: saned checks the identity (IP address) of the remote host only after the first communication took place (SANE_NET_INIT). So everyone can send that RPC, even if the remote host is not allowed to scan (not listed in saned.conf). CAN-2003-0774: saned lacks error checking nearly everywhere in the code. So connection drops are detected very late. If the drop of the connection isn't detected, the access to the internal wire buffer leaves the limits of the allocated memory. So random memory "after" the wire buffer is read which will be followed by a segmentation fault. CAN-2003-0775: If saned expects strings, it mallocs the memory necessary to store the complete string after it receives the size of the string. If the connection was dropped before transmitting the size, malloc will reserve an arbitrary size of memory. Depending on that size and the amount of memory available either malloc fails (->saned quits nicely) or a huge amount of memory is allocated. Swapping and OOM measures may occur depending on the kernel. CAN-2003-0776: saned doesn't check the validity of the RPC numbers it gets before getting the parameters. CAN-2003-0777: If debug messages are enabled and a connection is dropped, non-null-terminated strings may be printed and segmentation faults may occur. CAN-2003-0778: It's possible to allocate an arbitrary amount of memory on the server running saned even if the connection isn't dropped. At the moment this can not easily be fixed according to the author. Better limit the total amount of memory saned may use (ulimit).

stunnel: signal handler reentrancy DoS

Package(s):	stunnel	CVE #(s):	CAN-2002-1563
Created:	July 25, 2003	Updated:	November 25, 2003
Description:	Stunnel is a wrapper for network connections. It can be used to tunnel an unencrypted network connection over a secure connection (encrypted using SSL or TLS) or to provide a secure means of connecting to services that do not natively support encryption. When configured to listen for incoming connections (instead of being invoked by xinetd), stunnel can be configured to either start a thread or a child process to handle each new connection. If Stunnel is configured to start a new child process to handle each connection, it will receive a SIGCHLD signal when that child exits. Stunnel versions prior to 4.04 would perform tasks in the SIGCHLD signal handler which, if interrupted by another SIGCHLD signal, could be unsafe. This could lead to a denial of service.

Georgi Guninski found that these comments can be carefully crafted in order to call external programs. This could allow an attacker to create a text file such that when it is opened arbitrary commands are executed.

xinetd: Memory leak in xinetd 2.3.10

Package(s):	xinetd	CVE #(s):	CAN-2003-0211
Created:	May 13, 2003	Updated:	November 12, 2003
Description:	Xinetd is a 'master server' that is used to to accept service connection requests and start the appropriate servers. Because of a programming error, memory was allocated and never freed if a connection was refused for any reason. An attacker could exploit this flaw to crash the xinetd server, rendering all services it controls unavailable. In addition, other flaws in xinetd could cause incorrect operation in certain unusual server configurations. All users of xinetd are advised to update to xinetd-2.3.11 which is not vulnerable to these issues.

Interview: Brian Hatch (LinuxQuestions)

LinuxQuestions.org interviews Brian Hatch, author of Hacking Linux Exposed. "So true, not everyone can read and understand the code that they end up running, and not anyone can read all of the code that they end up running. There's a level of trust, and that's no different than when you run proprietary software. The big difference is the number of individuals who do view that code."

Release status

Kernel release status

The current development kernel is 2.6.0-test9, released by Linus on October 25. It consists almost entirely of important fixes, of course, but Linus also threw in Jeff Garzik's "libata" driver. As always, the long-format changlog has the details.

It seems a real 2.6.0 release could be getting close:

Linus's approach of restricting patches to the most important fixes should help to stabilize the kernel. It also is likely to mean, however, that there will be a substantial pile of patches waiting to go in after the 2.6.0 release.

2.6.0-test9 is, perhaps, unique in having its own press release, something that is not normally done for development kernels. OSDL, it seems, wants to be sure that the world knows where Linus and Andrew work these days.

Linus's BitKeeper tree, as of this writing, contains a relatively small number of fixes.

The current stable kernel is 2.4.22; Marcelo released 2.4.23-pre8 on October 22. Along with the usual fixes, this patch also includes an ACPI update, some driver updates, and a set of tmpfs fixes.

Mandrake Linux 9.2 and self-destructing CD-ROM drives

Upgrading to a new version of an operating system is always a bit of a mixed experience. The promise of new features, new applications, and better performance (one hopes) contends with the fear that the upgrade will break something that used to work. Even the most worried among us, however, do not normally worry about an upgrade causing hardware to self destruct. Those who have recent attempted to install Mandrake Linux 9.2 on a system containing an LG CD drive (shipped by Dell and numerous others) have gotten just that sort of surprise, however. An unpatched 9.2 system, it seems, can cause those drives to wipe out their firmware and cease to function.

This problem has been the centerpiece of a small flood of complaints about the stability of the 9.2 rele
