Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated firefox packages that fix several security issues are now
available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having critical security impact by the
Red Hat Security Response Team.

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-2009-1302, CVE-2009-1303, CVE-2009-1304, CVE-2009-1305)

Several flaws were found in the way malformed web content was
processed. A web page containing malicious content could execute
arbitrary JavaScript in the context of the site, possibly presenting
misleading data to a user, or stealing sensitive information such as
login credentials. (CVE-2009-0652, CVE-2009-1306, CVE-2009-1307,
CVE-2009-1308, CVE-2009-1309, CVE-2009-1310, CVE-2009-1312)

A flaw was found in the way Firefox saved certain web pages to a local
file. If a user saved the inner frame of a web page containing POST
data, the POST data could be revealed to the inner frame, possibly
surrendering sensitive information such as login credentials.
(CVE-2009-1311)

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 3.0.9. 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 3.0.9, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
take effect.
