Affected Products:

openSUSE 11.3

______________________________________________________________________________

 

An update that fixes 5 vulnerabilities is now available. It

includes two new package versions.

 

Description:

 

Mozilla Firefox was updated to version 3.6.23, 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)
