   An update that contains security fixes can now be
   installed. It includes one version update.

Description:

   Mozilla XULRunner was updated to version 1.9.2.23, fixing
   various bugs and security issues.

   MFSA 2011-36: Mozilla developers identified and fixed
   several memory safety bugs in the browser engine used in
   Firefox and other Mozilla-based products. Some of these
   bugs showed evidence of memory corruption under certain
   circumstances, and we presume that with enough effort at
   least some of these could be exploited to run arbitrary
   code.

   In general these flaws cannot be exploited through email in
   the Thunderbird and SeaMonkey products because scripting is
   disabled,, but are potentially a risk in browser or
   browser-like contexts in those products.

   Benjamin Smedberg, Bob Clary, and Jesse Ruderman reported
   memory safety problems that affected Firefox 3.6 and
   Firefox 6. (CVE-2011-2995)

   Josh Aas reported a potential crash in the plugin API that
   affected Firefox 3.6 only. (CVE-2011-2996)

   MFSA 2011-37: Mark Kaplan reported a potentially
   exploitable crash due to integer underflow when using a
   large JavaScript RegExp expression. We would also like to
   thank Mark for contributing the fix for this problem. (no
   CVE yet)

   MFSA 2011-38: Mozilla developer Boris Zbarsky reported that
   a frame named "location" could shadow the window.location
   object unless a script in a page grabbed a reference to the
   true object before the frame was created. Because some
   plugins use the value of window.location to determine the
   page origin this could fool the plugin into granting the
   plugin content access to another site or the local file
   system in violation of the Same Origin Policy. This flaw
   allows circumvention of the fix added for MFSA 2010-10.
   (CVE-2011-2999)

   MFSA 2011-39: Ian Graham of Citrix Online reported that
   when multiple Location headers were present in a redirect
   response Mozilla behavior differed from other browsers:
   Mozilla would use the second Location header while Chrome
   and Internet Explorer would use the first. Two copies of
   this header with different values could be a symptom of a
   CRLF injection attack against a vulnerable server. Most
   commonly it is the Location header itself that is
   vulnerable to the response splitting and therefore the copy
   preferred by Mozilla is more likely to be the malicious
   one. It is possible, however, that the first copy was the
   injected one depending on the nature of the server
   vulnerability.

   The Mozilla browser engine has been changed to treat two
   copies of this header with different values as an error
   condition. The same has been done with the headers
   Content-Length and Content-Disposition. (CVE-2011-3000)
   MFSA 2011-40: Mariusz Mlynski reported that if you could
   convince a user to hold down the Enter key--as part of a
   game or test, perhaps--a malicious page could pop up a
   download dialog where the held key would then activate the
   default Open action. For some file types this would be
   merely annoying (the equivalent of a pop-up) but other file
   types have powerful scripting capabilities. And this would
   provide an avenue for an attacker to exploit a
   vulnerability in applications not normally exposed to
   potentially hostile internet content.

   Holding enter allows arbitrary code execution due to
   Download Manager (CVE-2011-2372)
