Description

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

Multiple flaws were found in the location object implementation in Firefox. Malicious content could be used to perform cross-site scripting attacks, bypass the same-origin policy, or cause Firefox to execute arbitrary code. (CVE-2012-4194, CVE-2012-4195, CVE-2012-4196)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.10 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. Upstream acknowledges Mariusz Mlynski, moz_bug_r_a4, and Antoine Delignat-Lavaud as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which contain Firefox version 10.0.10 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.
