   * Miscellaneous memory safety hazards: Mozilla identified
   and fixed several memory safety bugs in the browser
   engine used in Firefox 4, Firefox 5 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.

   Aral Yaman reported a WebGL crash which affected Firefox
   4 and Firefox 5. (CVE-2011-2989)

   Vivekanand Bolajwar reported a JavaScript crash which
   affected Firefox 4 and Firefox 5. (CVE-2011-2991)

   Bert Hubert and Theo Snelleman of Fox-IT reported a crash
   in the Ogg reader which affected Firefox 4 and Firefox 5.
   (CVE-2011-2992)

   Mozilla developers and community members Robert Kaiser,
   Jesse Ruderman, moz_bug_r_a4, Mardeg, Gary Kwong, Christoph
   Diehl, Martijn Wargers, Travis Emmitt, Bob Clary and
   Jonathan Watt reported memory safety issues which affected
   Firefox 4 and Firefox 5. (CVE-2011-2985)


   * Unsigned scripts can call script inside signed JAR Rafael
   Gieschke reported that unsigned JavaScript could call
   into script inside a signed JAR thereby inheriting the
   identity of the site that signed the JAR as well as any
   permissions that a user had granted the signed JAR.
   (CVE-2011-2993)

   * String crash using WebGL shaders Michael Jordon of
   Context IS reported that an overly long shader program
   could cause a buffer overrun and crash in a string class
   used to store the shader source code. (CVE-2011-2988)

   * Heap overflow in ANGLE library Michael Jordon of Context
   IS reported a potentially exploitable heap overflow in
   the ANGLE library used by Mozilla's WebGL implementation.
   (CVE-2011-2987)

   * 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)

   * Credential leakage using Content Security Policy reports
   Mike Cardwell reported that Content Security Policy
   violation reports failed to strip out proxy authorization
   credentials from the list of request headers. Daniel
   Veditz reported that redirecting to a website with
   Content Security Policy resulted in the incorrect
   resolution of hosts in the constructed policy.
   (CVE-2011-2990)
   * Cross-origin data theft using canvas and Windows D2D
   nasalislarvatus3000 reported that when using Windows D2D
   hardware acceleration, image data from one domain could
   be inserted into a canvas and read by a different domain.
   (CVE-2011-2986)
