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)
