Mozilla Firefox was updated to version 3.6.20.
It fixes bugs and security issues. Following security issues were fixed: Mozilla Foundation Security Advisory 2011-30 - MFSA 2011-30 <<a rel="nofollow" href="http://www.mozilla.org/security/announce/2011/mfsa2011-30.h">http://www.mozilla.org/security/announce/2011/mfsa2011-30.h</a> tml>
Miscellaneous memory safety hazards
Mozilla developers and community members identified and fixed several memory safety bugs in the browser engine used in Firefox 3.6 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.
Gary Kwong, Igor Bukanov, Nils and Bob Clary reported memory safety issues which affected Firefox 3.6. (CVE-2011-2982)
Crash in SVGTextElement.getCharNumAtPosition()
Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that a SVG text manipulation routine contained a dangling pointer vulnerability. (CVE-2011-0084)
Privilege escalation using event handlers
Dangling pointer vulnerability in appendChild
Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that appendChild did not correctly account for DOM objects it operated upon and could be exploited to dereference an invalid pointer. (CVE-2011-2378)
Privilege escalation dropping a tab element in content area
Mozilla security researcher moz_bug_r_a4 reported that web content could receive chrome privileges if it registered for drop events and a browser tab element was dropped into the content area. (CVE-2011-2984)
Binary planting vulnerability in ThinkPadSensor::Startup
Security researcher Mitja Kolsek of Acros Security reported that ThinkPadSensor::Startup could potentially be exploited to load a malicious DLL into the running process. (CVE-2011-2980) (This issue is likely Windows only)
Private data leakage using RegExp.input
Security researcher shutdown reported that data from other domains could be read when RegExp.input was set. (CVE-2011-2983)
