Title:RedHat Security Advisory RHSA-2012:0710
The remote host is missing updates announced in
advisory RHSA-2012:0710.

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 drivers
with 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. You can find a link to the Mozilla
advisories in the References section of this erratum.

Red Hat would like to thank the Mozilla project for reporting these issues.
