Security
Another look at response times
Two weeks ago, this page compared the response times of several distributors to a small set of recent security issues. That article generated a number of comments and a fair amount of mail from people who felt that its conclusions were inaccurate. As before, the table shows the number of days required for each distributor to issue an update. For the purposes of this table, the clock starts when a vulnerability is disclosed, or when the first distributor alert is issued, whichever comes first. So, here is a new version of the response times table which takes those comments - and alerts issued after publication - into account:
Vulnerability Distributor Debian Fedora Gentoo Red Hat SUSE Ubuntu Apache mod_ssl 14 9 21 11 14 12 clamav 22 3 3 n/a 5 -- evolution -- 1 13 19 6 1 fetchmail 22 0 4 4 7 5 PCRE 13 4 14 18 16 3 PHP XML-RPC 9 4 5 6 7 4 PHP XML-RPC 2 18 10 9 4 15 5 ProFTPd 35 -- 4 n/a n/a n/a vim modeline -- 16 n/a? 28 n/a? 1
In the above table, numbers which are underlined reflect alerts issued after the previous version. Those which are, instead, bold are corrections for erroneous entries published two weeks ago.
As one can see, a number of corrections were required. One might conclude from this that your editor was being even more clueless than usual when compiling the previous version of the table. One would probably be right, but there is a little more to it than that. It turns out that putting together a table like this is a hard thing to do.
The previous version stated that Fedora had not issued an advisory for clamav. That is, in fact, true; no advisory ever came out. The clamav package in Fedora Extras was quietly replaced, however, shortly after the vulnerability was disclosed. In the presence of silent fixes, it is hard for users to know if they are vulnerable or not; this is doubly true in cases where security fixes are backported to previous releases of the affected package. Fedora Extras does not do backporting, but it still requires an alert administrator to know that, while clamav has been fixed, ProFTPd in Extras remains vulnerable.
Speaking of ProFTPd, your editor had seen that package in a SUSE distribution he had at hand, and assumed it was still distributed. That turns out not to be the case.
Both SUSE and Gentoo claim to not be affected by the vim modeline vulnerability because they ship versions with the modeline feature turned off by default. Turning off a possibly insecure feature is a good thing to do; it reflects a concern by the distributor for the security of its users. Some of those users, however, will certainly turn the feature back on. Others will be concerned by the fact that they are running software with a known, unpatched vulnerability, even if that vulnerability does not directly affect them. In such cases, it would make sense for the distributor to, at a minimum, issue an advisory explaining the situation. Putting out a fix would be better.
Other corrections above reflect simple screwups on your editor's part. Sorry.
The corrected table still shows some real patterns in the relative response times for security updates. There is value in this information. As time permits, LWN will be making changes to its security database to make the generation of this sort of table an easier and more accurate process. But a task which, in the presence of nice things like CVE numbers, should be relatively straightforward is likely to require a fair amount of time (and iterations) for the foreseeable future.
Security news
Mozilla Linux Command Line URL Parsing Security Flaw Reported (MozillaZine)
MozillaZine warns of a new firefox security problem; this one has to do with command line parsing. "For example, consider a Linux user who uses Firefox as his or her default Web browser and Mozilla Thunderbird as his or her default email client. An attacker could send an email to this user containing a link to http://local`find`host. When the user clicks on this link in Thunderbird, Firefox's URL-parsing shell script will be invoked and will execute the find command before calling Firefox to open the URL." The firefox 1.0.7 release contains the fix for this problem (and a few others).

a way that the receiving server processes it as a separate HTTP request.
This could allow the bypass of Web application firewall protection or lead
to cross-site scripting (XSS) attacks.
Marc Stern reported an off-by-one overflow in the mod_ssl CRL verification callback. In order to exploit this issue the Apache server would need to be configured to use a malicious certificate revocation list (CRL). | |||||||||||||||||||||||||||||||||||||||||

the key session joining function. Under certain user-triggerable
conditions, a semaphore was not released properly, which caused
processes which also attempted to join a key session to hang forever.
(CAN-2005-2098)
David Howells discovered a local Denial of Service vulnerability in the keyring allocator. A local attacker could exploit this to crash the kernel by attempting to add a specially crafted invalid keyring. (CAN-2005-2099) Balazs Scheidler discovered a local Denial of Service vulnerability in the xfrm_compile_policy() function. By calling setsockopt() with an invalid xfrm_user policy message, a local attacker could cause the kernel to write to an array beyond its boundaries, thus causing a kernel crash. (CAN-2005-2456) Tim Yamin discovered that the driver for compressed ISO file systems did not sufficiently validate the input data. By tricking an user into mounting a malicious CD-ROM with a specially crafted compressed ISO file system, he could cause a kernel crash. (CAN-2005-2457) It was discovered that the kernel's embedded zlib compression library was still vulnerable to two old vulnerabilities of the standalone zlib library. This library is used by various drivers and can also be used by third party modules, so the impact varies. (CAN-2005-2458, CAN-2005-2459) Peter Sandstrom discovered a remote Denial of Service vulnerability in the SNMP handler. Certain UDP packages lead to a function call with the wrong argument, which resulted in a crash of the network stack. (CAN-2005-2548) Herbert Xu discovered that the setsockopt() function was not restricted to privileged users. This allowed a local attacker to bypass intended IPSec policies, set invalid policies to exploit flaws like CAN-2005-2456, or cause a Denial of Service by adding policies until kernel memory is exhausted. Now the call is restricted to processes with the CAP_NET_ADMIN capability. (CAN-2005-2555) | ||||||||||||||||||||

libgadu: memory alignment bug
| Package(s): | libgadu | CVE #(s): | CAN-2005-2370 | |||||||||
| Created: | July 29, 2005 | Updated: | June 25, 2007 | |||||||||
| Description: | Szymon Zygmunt and Michal Bartoszkiewicz discovered a memory alignment error in libgadu (from ekg, console Gadu Gadu client, an instant messaging program) which is included in gaim, a multi-protocol instant messaging client, as well. This can not be exploited on the x86 architecture but on others, e.g. on Sparc and lead to a bus error, in other words a denial of service. | |||||||||||

libgd2: buffer overflows in PNG handling
| Package(s): | libgd2 | CVE #(s): | CAN-2004-0990 CAN-2004-0941 | |||||||||||||||||||||||||||||||||||||||||||||||||||
| Created: | October 29, 2004 | Updated: | June 28, 2006 | |||||||||||||||||||||||||||||||||||||||||||||||||||
| Description: | Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image. Most importantly, this library is commonly used in PHP. One possible target would be a PHP driven photo website that lets users upload images. Therefore this vulnerability might lead to privilege escalation to a web server's privileges. Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function. | |||||||||||||||||||||||||||||||||||||||||||||||||||||

libnet-ssleay-perl: weakened cryptographic operations
| Package(s): | libnet-ssleay-perl | CVE #(s): | CAN-2005-0106 | ||||||
| Created: | May 3, 2005 | Updated: | January 27, 2006 | ||||||
| Description: | Javier Fernandez-Sanguino Pena discovered that this library used the file /tmp/entropy as a fallback entropy source if a proper source was not set in the environment variable EGD_PATH. This can potentially lead to weakened cryptographic operations if an attacker provides a /tmp/entropy file with known content. | ||||||||
