Security issues were identified and fixed in mozilla firefox and thunderbird :

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent the starting of a download in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted website (CVE-2011-2372).

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2011-2995).

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2011-2997).

Mozilla Firefox before 3.6.23 and 4.x through 5, Thunderbird before 6.0, and SeaMonkey before 2.3 do not properly handle location as the name of a frame, which allows remote attackers to bypass the Same Origin Policy via a crafted website, a different vulnerability than CVE-2010-0170 (CVE-2011-2999).

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not properly handle HTTP responses that contain multiple Location, Content-Length, or Content-Disposition headers, which makes it easier for remote attackers to conduct HTTP response splitting attacks via crafted header values (CVE-2011-3000).

Mozilla Firefox 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent manual add-on installation in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site that triggers an unspecified internal error (CVE-2011-3001).

Almost Native Graphics Layer Engine (ANGLE), as used in Mozilla Firefox before 7.0 and SeaMonkey before 2.4, does not validate the return value of a GrowAtomTable function call, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger a memory-allocation error and a resulting buffer overflow (CVE-2011-3002).

Mozilla Firefox before 7.0 and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an unspecified WebGL test case that triggers a memory-allocation error and a resulting out-of-bounds write operation (CVE-2011-3003).

The JSSubScriptLoader in Mozilla Firefox 4.x through 6 and SeaMonkey before 2.4 does not properly handle XPCNativeWrappers during calls to the loadSubScript method in an add-on, which makes it easier for remote attackers to gain privileges via a crafted website that leverages certain unwrapping behavior (CVE-2011-3004).

Use-after-free vulnerability in Mozilla Firefox 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OGG headers in a .ogg file (CVE-2011-3005).

YARR, as used in Mozilla Firefox before 7.0, Thunderbird before 7.0, and SeaMonkey before 2.4, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted JavaScript (CVE-2011-3232).

Integer underflow in Mozilla Firefox 3.6.x before 3.6.23 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via JavaScript code containing a large RegExp expression (CVE-2011-3867).

From Red Hat Security Advisory 2011:1344 :

Updated SeaMonkey packages that fix two security issues are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

SeaMonkey is an open source web browser, email and newsgroup client, IRC chat client, and HTML editor.

A flaw was found in the way SeaMonkey handled frame objects with certain names. An attacker could use this flaw to cause a plug-in to grant its content access to another site or the local file system, violating the same-origin policy. (CVE-2011-2999)

An integer underflow flaw was found in the way SeaMonkey handled large JavaScript regular expressions. A web page containing malicious JavaScript could cause SeaMonkey to access already freed memory, causing SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-2998)

All SeaMonkey users should upgrade to these updated packages, which correct these issues. After installing the update, SeaMonkey must be restarted for the changes to take effect.

Mozilla XULRunner was updated to version 1.9.2.23, fixing various bugs and security issues.

MFSA 2011-36: Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled,, but are potentially a risk in browser or browser-like contexts in those products.

Benjamin Smedberg, Bob Clary, and Jesse Ruderman reported memory safety problems that affected Firefox 3.6 and Firefox 6.
(CVE-2011-2995)

Josh Aas reported a potential crash in the plugin API that affected Firefox 3.6 only. (CVE-2011-2996)

MFSA 2011-37: Mark Kaplan reported a potentially exploitable crash due to integer underflow when using a large JavaScript RegExp expression.
We would also like to thank Mark for contributing the fix for this problem. (no CVE yet)

MFSA 2011-38: Mozilla developer Boris Zbarsky reported that a frame named 'location' could shadow the window.location object unless a script in a page grabbed a reference to the true object before the frame was created. Because some plugins use the value of window.location to determine the page origin this could fool the plugin into granting the plugin content access to another site or the local file system in violation of the Same Origin Policy. This flaw allows circumvention of the fix added for MFSA 2010-10.
(CVE-2011-2999)

MFSA 2011-39: Ian Graham of Citrix Online reported that when multiple Location headers were present in a redirect response Mozilla behavior differed from other browsers: Mozilla would use the second Location header while Chrome and Internet Explorer would use the first. Two copies of this header with different values could be a symptom of a CRLF injection attack against a vulnerable server. Most commonly it is the Location header itself that is vulnerable to the response splitting and therefore the copy preferred by Mozilla is more likely to be the malicious one. It is possible, however, that the first copy was the injected one depending on the nature of the server vulnerability.

The Mozilla browser engine has been changed to treat two copies of this header with different values as an error condition. The same has been done with the headers Content-Length and Content-Disposition.
(CVE-2011-3000) MFSA 2011-40: Mariusz Mlynski reported that if you could convince a user to hold down the Enter key--as part of a game or test, perhaps--a malicious page could pop up a download dialog where the held key would then activate the default Open action. For some file types this would be merely annoying (the equivalent of a pop-up) but other file types have powerful scripting capabilities. And this would provide an avenue for an attacker to exploit a vulnerability in applications not normally exposed to potentially hostile internet content.

Holding enter allows arbitrary code execution due to Download Manager (CVE-2011-2372)

Mozilla SeaMonkey was updated to version 2.4, fixing various bugs and security issues.

MFSA 2011-36: Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

Benjamin Smedberg, Bob Clary, and Jesse Ruderman reported memory safety problems that affected Firefox 3.6 and Firefox 6.
(CVE-2011-2995)

Bob Clary, Andrew McCreight, Andreas Gal, Gary Kwong, Igor Bukanov, Jason Orendorff, Jesse Ruderman, and Marcia Knous reported memory safety problems that affected Firefox 6, fixed in Firefox 7.
(CVE-2011-2997)

MFSA 2011-38: Mozilla developer Boris Zbarsky reported that a frame named 'location' could shadow the window.location object unless a script in a page grabbed a reference to the true object before the frame was created. Because some plugins use the value of window.location to determine the page origin this could fool the plugin into granting the plugin content access to another site or the local file system in violation of the Same Origin Policy.

For some file types this would be merely annoying (the equivalent of a pop-up) but other file types have powerful scripting capabilities. And this would provide an avenue for an attacker to exploit a vulnerability in applications not normally exposed to potentially hostile internet content.

Mariusz also reported a similar flaw with manual plugin installation using the PLUGINSPAGE attribute. It was possible to create an internal error that suppressed a confirmation dialog, such that holding enter would lead to the installation of an arbitrary add-on. (This variant did not affect Firefox 3.6)

Holding enter allows arbitrary code execution due to Download Manager (CVE-2011-2372)

Holding enter allows arbitrary extension installation (CVE-2011-3001)

MFSA 2011-41: Michael Jordon of Context IS reported that in the ANGLE library used by WebGL the return value from GrowAtomTable() was not checked for errors. If an attacker could cause requests that exceeded the available memeory those would fail and potentially lead to a buffer overrun as subsequent code wrote into the non-allocated space.
(CVE-2011-3002)

Ben Hawkes of the Google Security Team reported a WebGL test case that demonstrated an out of bounds write after an allocation failed.
(CVE-2011-3003)

MFSA 2011-42: Security researcher Aki Helin reported a potentially exploitable crash in the YARR regular expression library used by JavaScript. (CVE-2011-3232)

MFSA 2011-43: David Rees reported that the JSSubScriptLoader (a feature used by some add-ons) was 'unwrapping' XPCNativeWrappers when they were used as the scope parameter to loadSubScript(). Without the protection of the wrappers the add-on could be vulnerable to privilege escalation attacks from malicious web content. Whether any given add-on were vulnerable would depend on how the add-on used the feature and whether it interacted directly with web content, but we did find at least one vulnerable add-on and presumer there are more.
(CVE-2011-3004)

The unwrapping behavior was a change introduced during Firefox 4 development. Firefox 3.6 and earlier versions are not affected.

MFSA 2011-44: sczimmer reported that Firefox crashed when loading a particular .ogg file. This was due to a use-after-free condition and could potentially be exploited to install malware. (CVE-2011-3005)

This vulnerability does not affect Firefox 3.6 or earlier.

MFSA 2011-45: University of California, Davis researchers Liang Cai and Hao Chen presented a paper at the 2011 USENIX HotSec workshop on inferring keystrokes from device motion data on mobile devices. Web pages can now receive data similar to the apps studied in that paper and likely present a similar risk. We have decided to limit motion data events to the currently-active tab to prevent the possibility of background tabs attempting to decipher keystrokes the user is entering into the foreground tab.
