Topic

Updated firefox packages that fix several security issues are now available
for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical

which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

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 with the privileges of the user running
Firefox. (CVE-2013-1701)

A flaw was found in the way Firefox generated Certificate Request Message
Format (CRMF) requests. An attacker could use this flaw to perform
cross-site scripting (XSS) attacks or execute arbitrary code with the
privileges of the user running Firefox. (CVE-2013-1710)

A flaw was found in the way Firefox handled the interaction between frames
and browser history. An attacker could use this flaw to trick Firefox into
treating malicious content as if it came from the browser history, allowing
for XSS attacks. (CVE-2013-1709)

It was found that the same-origin policy could be bypassed due to the way
Uniform Resource Identifiers (URI) were checked in JavaScript. An attacker
could use this flaw to perform XSS attacks, or install malicious add-ons
from third-party pages. (CVE-2013-1713)

It was found that web workers could bypass the same-origin policy. An
attacker could use this flaw to perform XSS attacks. (CVE-2013-1714)

It was found that, in certain circumstances, Firefox incorrectly handled
Java applets. If a user launched an untrusted Java applet via Firefox, the
applet could use this flaw to obtain read-only access to files on the
user's local system. (CVE-2013-1717)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Jeff Gilbert, Henrik Skupin, moz_bug_r_a4, Cody
Crews, Federico Lanusse, and Georgi Guninski as the original reporters of
these issues.

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 17.0.8 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 17.0.8 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
