3. Description:

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

A use-after-free flaw was found in Firefox. Under low memory conditions,
visiting a web page containing malicious content could result in Firefox
executing arbitrary code with the privileges of the user running Firefox.
(CVE-2009-1571)

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-2010-0159, CVE-2010-0160)

Two flaws were found in the way certain content was processed. An attacker
could use these flaws to create a malicious web page that could bypass the
same-origin policy, or possibly run untrusted JavaScript. (CVE-2009-3988,
CVE-2010-0162)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 3.0.18. 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 3.0.18, which corrects these issues. After installing the
update, Firefox must be restarted for the changes to take effect.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
