CentOS Errata and Security Advisory CESA-2009:1162

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 as the user running Firefox.
(CVE-2009-2462, CVE-2009-2463, CVE-2009-2464, CVE-2009-2465, CVE-2009-2466,
CVE-2009-2467, CVE-2009-2469, CVE-2009-2471)

Several flaws were found in the way Firefox handles malformed JavaScript
code. A website containing malicious content could launch a cross-site
scripting (XSS) attack or execute arbitrary JavaScript with the permissions
of another website. (CVE-2009-2472)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.0.12. You can find a link to the Mozilla
advisories in the References section of this errata.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 3.0.12, which corrects these issues. After installing the
update, Firefox must be restarted for the changes to take effect.
