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 6.

The Red Hat Security Response Team has rated this update as having
critical security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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

A race condition flaw was found in the way Firefox handled Document
Object Model (DOM) element properties. Malicious HTML content could
cause Firefox to crash or, potentially, execute arbitrary code with
the privileges of the user running Firefox. (CVE-2010-3765)

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-2010-3175, CVE-2010-3176, CVE-2010-3179,
CVE-2010-3183, CVE-2010-3180)

A flaw was found in the way the Gopher parser in Firefox converted
text into HTML. A malformed file name on a Gopher server could, when
accessed by a victim running Firefox, allow arbitrary JavaScript to be
executed in the context of the Gopher domain. (CVE-2010-3177)

A same-origin policy bypass flaw was found in Firefox. An attacker
could create a malicious web page that, when viewed by a victim, could
steal private data from a different website the victim had loaded with
Firefox. (CVE-2010-3178)

A flaw was found in the script that launches Firefox. The
LD_LIBRARY_PATH variable was appending a '.' character, which could
allow a local attacker to execute arbitrary code with the privileges
of a different user running Firefox, if that user ran Firefox from
within an attacker-controlled directory. (CVE-2010-3182)

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 3.6.11 and 3.6.12. You can find links
to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which
contain Firefox version 3.6.12, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
take effect.
