Synopsis: Critical: firefox security update
Issue Date: 2012-06-05
CVE Numbers: CVE-2011-3101
 CVE-2012-1944
 CVE-2012-1945
 CVE-2012-1946
 CVE-2012-1940

Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.

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-2011-3101, CVE-2012-1937, CVE-2012-1938, CVE-2012-1939,
CVE-2012-1940, CVE-2012-1941, CVE-2012-1946, CVE-2012-1947)

Note: CVE-2011-3101 only affected users of certain NVIDIA display driverswith graphics cards that have hardware acceleration enabled.

It was found that the Content Security Policy (CSP) implementation in
Firefox no longer blocked Firefox inline event handlers. A remote attacker
could use this flaw to possibly bypass a web application's intended
restrictions, if that application relied on CSP to protect against flaws
such as cross-site scripting (XSS). (CVE-2012-1944)

If a web server hosted HTML files that are stored on a Microsoft Windows
share, or a Samba share, loading such files with Firefox could result in
Windows shortcut files (.lnk) in the same share also being loaded. An
attacker could use this flaw to view the contents of local files and
directories on the victim's system. This issue also affected users opening
HTML files from Microsoft Windows shares, or Samba shares, that are mounted
on their systems. (CVE-2012-1945)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 10.0.5 ESR.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 10.0.5 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
