______________________________________________________________________________

Announcement ID:    openSUSE-SU-2011:0935-2
Rating:             important
References:         #712224 
Affected Products:
                    openSUSE 11.4
                    openSUSE 11.3
______________________________________________________________________________

   An update that contains security fixes can now be
   installed. It includes three new package versions.

Description:

   Mozilla Thunderbird was updated to 3.1.12 fixing various
   bugs and  security issues:

   Mozilla Foundation Security Advisory 2011-32 (MFSA 2011-32)
   http://www.mozilla.org/security/announce/2011/mfsa2011-32.ht
   ml

   Many of the issues listed below are not exploitable through
   mail since JavaScript is disabled by default in
   Thunderbird. These particular issues may be triggered while
   viewing RSS feeds and displaying full remote content rather
   than the feed summary. Addons that expose browser
   functionality may also enable such issues to be exploited.

   * Miscellaneous memory safety hazards (rv:1.9.2.20)

   Mozilla developers and community members identified and
   fixed several memory safety bugs in the browser engine used
   in Thunderbird 3.1 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 Thunderbird 3.1.
   (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)

   * 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)
