Mozilla Firefox was updated to update 3.6.13 fixing several security issues.

MFSA 2010-74: 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.

Jesee Ruderman, Andreas Gal, Nils, and Brian Hackett reported memory safety problems that affected Firefox 3.6 and Firefox 3.5.
(CVE-2010-3776) Igor Bukanov reported a memory safety problem that was fixed in Firefox 3.6 only. (CVE-2010-3777) Jesse Ruderman reported a crash which affected Firefox 3.5 only. (CVE-2010-3778)

MFSA 2010-75 / CVE-2010-3769: Dirk Heinrich reported that on Windows platforms when document.write() was called with a very long string a buffer overflow was caused in line breaking routines attempting to process the string for display. Such cases triggered an invalid read past the end of an array causing a crash which an attacker could potentially use to run arbitrary code on a victim's computer.

MFSA 2010-76 / CVE-2010-3771: Security researcher echo reported that a web page could open a window with an about:blank location and then inject an <isindex> element into that page which upon submission would redirect to a chrome: document. The effect of this defect was that the original page would wind up with a reference to a chrome-privileged object, the opened window, which could be leveraged for privilege escalation attacks.

Mozilla security researcher moz_bug_r_a4 provided proof-of-concept code demonstrating how the above vulnerability could be used to run arbitrary code with chrome privileges.

MFSA 2010-77 / CVE-2010-3772: Security researcher wushi of team509 reported that when a XUL tree had an HTML <div> element nested inside a <treechildren> element then code attempting to display content in the XUL tree would incorrectly treat the <div> element as a parent node to tree content underneath it resulting in incorrect indexes being calculated for the child content. These incorrect indexes were used in subsequent array operations which resulted in writing data past the end of an allocated buffer. An attacker could use this issue to crash a victim's browser and run arbitrary code on their machine.

MFSA 2010-78 / CVE-2010-3768: Mozilla added the OTS font sanitizing library to prevent downloadable fonts from exposing vulnerabilities in the underlying OS font code. This library mitigates against several issues independently reported by Red Hat Security Response Team member Marc Schoenefeld and Mozilla security researcher Christoph Diehl.

MFSA 2010-79 / CVE-2010-3775: Security researcher Gregory Fleischer reported that when a Java LiveConnect script was loaded via a data:
URL which redirects via a meta refresh, then the resulting plugin object was created with the wrong security principal and thus received elevated privileges such as the abilities to read local files, launch processes, and create network connections.

MFSA 2010-80 / CVE-2010-3766: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that a nsDOMAttribute node can be modified without informing the iterator object responsible for various DOM traversals. This flaw could lead to a inconsistent state where the iterator points to an object it believes is part of the DOM but actually points to some other object. If such an object had been deleted and its memory reclaimed by the system, then the iterator could be used to call into attacker-controlled memory.

MFSA 2010-81 / CVE-2010-3767: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that JavaScript arrays were vulnerable to an integer overflow vulnerability. The report demonstrated that an array could be constructed containing a very large number of items such that when memory was allocated to store the array items, the integer value used to calculate the buffer size would overflow resulting in too small a buffer being allocated. Subsequent use of the array object could then result in data being written past the end of the buffer and causing memory corruption.

MFSA 2010-82 / CVE-2010-3773: Mozilla security researcher moz_bug_r_a4 reported that the fix for CVE-2010-0179 could be circumvented permitting the execution of arbitrary JavaScript with chrome privileges.

MFSA 2010-83 / CVE-2010-3774: Google security researcher Michal Zalewski reported that when a window was opened to a site resulting in a network or certificate error page, the opening site could access the document inside the opened window and inject arbitrary content. An attacker could use this bug to spoof the location bar and trick a user into thinking they were on a different site than they actually were.

MFSA 2010-84 / CVE-2010-3770: Security researchers Yosuke Hasegawa and Masatoshi Kimura reported that the x-mac-arabic, x-mac-farsi and x-mac-hebrew character encodings are vulnerable to XSS attacks due to some characters being converted to angle brackets when displayed by the rendering engine. Sites using these character encodings would thus be potentially vulnerable to script injection attacks if their script filtering code fails to strip out these specific characters.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2010-3766, CVE-2010-3767, CVE-2010-3772, CVE-2010-3776, CVE-2010-3777)

A flaw was found in the way Firefox handled malformed JavaScript. A website with an object containing malicious JavaScript could cause Firefox to execute that JavaScript with the privileges of the user running Firefox. (CVE-2010-3771)

This update adds support for the Sanitiser for OpenType (OTS) library to Firefox. This library helps prevent potential exploits in malformed OpenType fonts by verifying the font file prior to use.
(CVE-2010-3768)

A flaw was found in the way Firefox loaded Java LiveConnect scripts.
Malicious web content could load a Java LiveConnect script in a way that would result in the plug-in object having elevated privileges, allowing it to execute Java code with the privileges of the user running Firefox. (CVE-2010-3775)

It was found that the fix for CVE-2010-0179 was incomplete when the Firebug add-on was used. If a user visited a website containing malicious JavaScript while the Firebug add-on was enabled, it could cause Firefox to execute arbitrary JavaScript with the privileges of the user running Firefox. (CVE-2010-3773)

A flaw was found in the way Firefox presented the location bar to users. A malicious website could trick a user into thinking they are visiting the site reported by the location bar, when the page is actually content controlled by an attacker. (CVE-2010-3774)

A cross-site scripting (XSS) flaw was found in the Firefox x-mac-arabic, x-mac-farsi, and x-mac-hebrew character encodings.
Certain characters were converted to angle brackets when displayed. If server-side script filtering missed these cases, it could result in Firefox executing JavaScript code with the permissions of a different website. (CVE-2010-3770)

After installing the update, Firefox must be restarted for the changes to take effect.
