Medium Nessus Plugin ID 36213
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated 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)
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.
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.
SolutionUpdate the affected packages.
