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)

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.

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.

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

This erratum upgrades Firefox from version 3.0.19 to version 3.6.4.
Due to the requirements of Firefox 3.6.4, this erratum also provides a number of other updated packages, including esc, totem, and yelp.

This erratum also contains multiple bug fixes and numerous enhancements. Space precludes documenting these changes in this advisory.
