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-2011-2982)

A dangling pointer flaw was found in the Firefox Scalable Vector
Graphics (SVG) text manipulation routine. A web page containing a
malicious SVG image could cause Firefox to crash or, potentially,
execute arbitrary code with the privileges of the user running Firefox.
(CVE-2011-0084)

A dangling pointer flaw was found in the way Firefox handled a certain
Document Object Model (DOM) element. 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-2011-2378)

A flaw was found in the event management code in Firefox. A website
containing malicious JavaScript could cause Firefox to execute that
JavaScript with the privileges of the user running Firefox. (CVE-2011-2981)

A flaw was found in the way Firefox handled malformed JavaScript. A web
page containing malicious JavaScript could cause Firefox to access
already freed memory, causing Firefox to crash or, potentially, execute
arbitrary code with the privileges of the user running Firefox.
(CVE-2011-2983)

It was found that a malicious web page could execute arbitrary code with
the privileges of the user running Firefox if the user dropped a tab
onto the malicious web page. (CVE-2011-2984)

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 3.6.20. 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 3.6.20, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to take
effect.
