Security
Cascading security updates
When following the distributions' security updates on a daily basis, as we do at LWN, certain days are more work than others. Two weeks ago we had a rather full update with no less than 28 packages updated for Fedora (most of those for both F7 and F8), along with a handful of updates from other distributions. It turns out that the majority of the Fedora updates had a single cause: a set of serious vulnerabilities in Mozilla Firefox.
How does a single update to an application ripple so far that more than a dozen packages have to be rebuilt? One would think there would be shared libraries that would get updated, with applications picking up those changes the next time they are run. That is, in theory, how things are supposed to work, but in this case, the underlying libraries have no fixed application binary interface (ABI). So, changes to those libraries require any applications that use them to be rebuilt and retested.
Gecko is the rendering engine used by Mozilla in their products to display HTML. Various other packages have started using it as well because of its speed and standards compliance. Because Mozilla sometimes breaks the ABI between releases, even minor releases, distributions may be stuck rebuilding those applications when a new version of the library is released. Normally, that only happens when packaging a new version of the distribution—or when serious security flaws are found.
Mozilla's solution for this problem is XULRunner which will provide a stable ABI for applications. As XULRunner and its companion libxul become more widely available, the applications that currently link to the Gecko libraries will presumably switch to avoid these kinds of problems in the future. It is highly unlikely that we have seen the last security problem in the Gecko engine, so reducing the cascade that results from finding one would be welcome.
Because of problems with the ABI changing in the past, Fedora chooses to make the applications' library version number exactly track the Mozilla release number. Some other distributions do not do that, so unless the ABI does change, they do not need to update each package that uses the libraries. This has some advantages, but could lead to broken applications if an ABI change goes unnoticed.
We have also seen similar cascades of updates, most notably from the xpdf PDF viewer. Unlike Gecko, there is no library for xpdf, leading multiple applications to include its source into their own. When a flaw is found, several different applications (cups, gpdf, etc.) across all distributions need to be updated immediately, leading to a similar effect as was seen with the Gecko vulnerabilities. Hopefully, over time, the development of the poppler library will mitigate this problem somewhat.
There are lots of good reasons to separate code into components where possible, but security is an important one. Creating and maintaining an ABI is sometimes difficult, but generally worth the trouble. Imagine the chaos that could result from a security vulnerability requiring an ABI change in glibc.
Security news
Cold Reboot Attacks on Disk Encryption
Ed Felten's Freedom to Tinker weblog has a report on research he and his colleagues have done on subverting whole disk encryption by reading the keys from RAM after the machine has been power-cycled. "The root of the problem lies in an unexpected property of today’s DRAM memories. DRAMs are the main memory chips used to store data while the system is running. Virtually everybody, including experts, will tell you that DRAM contents are lost when you turn off the power. But this isn't so. Our research shows that data in DRAM actually fades out gradually over a period of seconds to minutes, enabling an attacker to read the full contents of memory by cutting power and then rebooting into a malicious operating system."
Security reports
Risk report: Three years of Red Hat Enterprise Linux 4
Red Hat has published an updated version of its risk report for RHEL4, summarizing the security vulnerabilities in that distribution for the last three years and how Red Hat responded to them. "Fixes for 81% of critical flaws were available from Red Hat Network at latest one calendar day after public disclosure of the flaw. 63% of the critical flaws were fixed on the very same day. This fast response time is a deliberate goal of the Red Hat Security Response Team and forms an essential part of reducing customer risk from critical flaws." It would be nice if all distributors would produce an occasional report like this.

website could force arbitrary files from the user's computer to be
uploaded without consent. (CVE-2008-0414)

| Description: | A cross-site scripting flaw was found in the way Firefox handled the
jar: URI scheme. It was possible for a malicious website to leverage this
flaw and conduct a cross-site scripting attack against a user running
Firefox. (CVE-2007-5947)
Several flaws were found in the way Firefox processed certain malformed web content. A webpage containing malicious content could cause Firefox to crash, or potentially execute arbitrary code as the user running Firefox. (CVE-2007-5959) A race condition existed when Firefox set the "window.location" property for a webpage. This flaw could allow a webpage to set an arbitrary Referer header, which may lead to a Cross-site Request Forgery (CSRF) attack against websites that rely only on the Referer header for protection.

| Description: | From the Red Hat advisory:
Several flaws were found in the way Firefox processed certain malformed web
content. A webpage containing malicious content could cause Firefox to
crash, or potentially execute arbitrary code as the user running Firefox.
(CVE-2008-0412, CVE-2008-0413, CVE-2008-0415, CVE-2008-0419)
Several flaws were found in the way Firefox displayed malformed web content. A webpage containing specially-crafted content could trick a user into surrendering sensitive information. (CVE-2008-0591, CVE-2008-0593) A flaw was found in the way Firefox stored password data. If a user saves login information for a malicious website, it could be possible to corrupt the password database, preventing the user from properly accessing saved password data. (CVE-2008-0417) A flaw was found in the way Firefox handles certain chrome URLs. If a user has certain extensions installed, it could allow a malicious website to steal sensitive session data. Note: this flaw does not affect a default installation of Firefox. (CVE-2008-0418) A flaw was found in the way Firefox saves certain text files. If a website offers a file of type "plain/text", rather than "text/plain", Firefox will not show future "text/plain" content to the user in the browser, forcing them to save those files locally to view the content.
