openSUSE Security Update : MozillaFirefox (MozillaFirefox-4457)
Critical Nessus Plugin ID 75944
SynopsisThe remote openSUSE host is missing a security update.
DescriptionMozilla Firefox was updated to the 4.0.1 security release.
MFSA 2011-12: 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. Credits
Mozilla developers Boris Zbarsky, Gary Kwong, Jesse Ruderman, Michael Wu, Nils, Scoobidiver, and Ted Mielczarek reported memory safety issues which affected Firefox 4. (CVE-2011-0079)
Mozilla developer Scoobidiver reported a memory safety issue which affected Firefox 4 and Firefox 3.6 (CVE-2011-0081)
Ian Beer reported a crash that affected Firefox 4, Firefox 3.6 and Firefox 3.5. (CVE-2011-0070)
MFSA 2011-17 / CVE-2011-0068: Two crashes that could potentially be exploited to run malicious code were found in the WebGL feature and fixed in Firefox 4.0.1. In addition the WebGLES libraries could potentially be used to bypass a security feature of recent Windows versions. The WebGL feature was introduced in Firefox 4; older versions are not affected by these issues.
Nils reported that the WebGLES libraries in the Windows version of Firefox were compiled without ASLR protection. An attacker who found an exploitable memory corruption flaw could then use these libraries to bypass ASLR on Windows Vista and Windows 7, making the flaw as exploitable on those platforms as it would be on Windows XP or other platforms.
Mozilla researcher Christoph Diehl reported a potentially exploitable buffer overflow in the WebGLES library
Yuri Ko reported a potentially exploitable overwrite in the WebGLES library to the Chrome Secuity Team. We thank them for coordinating with us on this fix.
MFSA 2011-18 / CVE-2011-1202: Chris Evans of the Chrome Security Team reported that the XSLT generate-id() function returned a string that revealed a specific valid address of an object on the memory heap. It is possible that in some cases this address would be valuable information that could be used by an attacker while exploiting a different memory corruption but, in order to make an exploit more reliable or work around mitigation features in the browser or operating system.
SolutionUpdate the affected MozillaFirefox packages.
