   An update that fixes 7 vulnerabilities is now available. It
   includes two new package versions.

Description:

   Mozilla Firefox was updated to version 3.6.20.

   It fixes bugs and security issues. Following security
   issues were fixed:
   http://www.mozilla.org/security/announce/2011/mfsa2011-30.ht
   ml Mozilla Foundation Security Advisory 2011-30 (MFSA
   2011-30)

   * 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

   Mozilla security researcher moz_bug_r_a_4 reported a
   vulnerability in  event management code that would permit
   JavaScript to be run in the wrong context, including that
   of a different website or potentially in a
   chrome-privileged context. (CVE-2011-2981)

   * 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)
