From Red Hat Security Advisory 2010:0500 :

An updated firefox package that addresses security issues, fixes bugs, adds numerous enhancements, and upgrades Firefox to version 3.6.4, is 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.

Mozilla Firefox is an open source web browser.

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-2010-1121, CVE-2010-1200, CVE-2010-1202, CVE-2010-1203)

A flaw was found in the way browser plug-ins interact. It was possible for a plug-in to reference the freed memory from a different plug-in, resulting in the execution of arbitrary code with the privileges of the user running Firefox. (CVE-2010-1198)

Several integer overflow 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-2010-1196, CVE-2010-1199)

A focus stealing flaw was found in the way Firefox handled focus changes. A malicious website could use this flaw to steal sensitive data from a user, such as usernames and passwords. (CVE-2010-1125)

A flaw was found in the way Firefox handled the 'Content-Disposition:
attachment' HTTP header when the 'Content-Type: multipart' HTTP header was also present. A website that allows arbitrary uploads and relies on the 'Content-Disposition: attachment' HTTP header to prevent content from being displayed inline, could be used by an attacker to serve malicious content to users. (CVE-2010-1197)

A flaw was found in the Firefox Math.random() function. This function could be used to identify a browsing session and track a user across different websites. (CVE-2008-5913)

A flaw was found in the Firefox XML document loading security checks.
Certain security checks were not being called when an XML document was loaded. This could possibly be leveraged later by an attacker to load certain resources that violate the security policies of the browser or its add-ons. Note that this issue cannot be exploited by only loading an XML document. (CVE-2010-0182)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.6.4. You can find a link to the Mozilla advisories in the References section of this erratum.

This erratum upgrades Firefox from version 3.0.19 to version 3.6.4, and as such, contains multiple bug fixes and numerous enhancements.
Space precludes documenting these changes in this advisory. For details concerning these changes, refer to the Firefox Release Notes links in the References section of this erratum.

Important: Firefox 3.6.4 is not completely backwards-compatible with all Mozilla Add-ons and Firefox plug-ins that worked with Firefox 3.0.19. Firefox 3.6 checks compatibility on first-launch, and, depending on the individual configuration and the installed Add-ons and plug-ins, may disable said Add-ons and plug-ins, or attempt to check for updates and upgrade them. Add-ons and plug-ins may have to be manually updated.

All Firefox users should upgrade to this updated package, which contains Firefox version 3.6.4. After installing the update, Firefox must be restarted for the changes to take effect.

The installed version of Firefox 3.6.x is earlier than 3.6.2.  Such versions are potentially affected by multiple security issues :
 
  - The WOFF decoder contains an integer overflow in a font     decompression routine. (MFSA 2010-08)

  - Deleted image frames are reused when handling     'multipart/x-mixed-replace' images. (MFSA 2010-09)

  - The 'window.location' object is made a normal     overridable object. (MFSA 2010-10)

  - Multiple crashes can result in arbitrary code execution.
    (MFSA 2010-11)

  - A cross-site scripting issue when using     'addEventListener' and 'setTimeout' on a wrapped object.     (MFSA 2010-12)

  - Documents fail to call certain security checks when     attempting to preload images. (MFSA 2010-13)

  - It is possible to corrupt a user's XUL cache.     (MFSA 2010-14)

  - The asynchronous Authorization Prompt is not always     attached to the correct window. (MFSA 2010-15)   
  - Multiple crashes can result in arbitrary code execution.
    (MFSA 2010-16)

  - An error exists in the way '<option>' elements are     inserted into a XUL tree '<optgroup>' (MFSA 2010-18)

  - An error exists in the implementation of the     'windows.navigator.plugins' object. (MFSA 2010-19)

  - A browser applet can be used to turn a simple mouse     click into a drag-and-drop action, potentially resulting     in the unintended loading of resources in a user's     browser. (MFSA 2010-20)

  - Session renegotiations are not handled properly, which     can be exploited to insert arbitrary plaintext by a     man-in-the-middle. (MFSA 2010-22)

  - When an image points to a resource that redirects to a     'mailto:' URL, the external mail handler application is     launched. (MFSA 2010-23)     
  - XML documents fail to call certain security checks when     loading new content. (MFSA 2010-024)

MFSA 2010-08 WOFF heap corruption due to integer overflow

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.
