firefox, xulrunner security update

CentOS Errata and Security Advisory CESA-2013:1140

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
