Red Hat Security Advisory: firefox security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:0710 Final 1 1 2012-06-05T19:56:00Z Current version 2012-06-05T19:56:00Z 2012-06-05T19:56:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-06-05T20:57:02Z Updated firefox packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6. 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. 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.

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. Please see https://www.redhat.com/footer/terms-of-use.html Copyright © 2012 Red Hat, Inc. All rights reserved.
