SuSE: New Firefox packages fix remote code execution

Mozilla Firefox was updated to version 6. 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. Aral Yaman reported a WebGL crash which affected Firefox 4 and Firefox 5. Vivekanand Bolajwar reported a JavaScript crash which affected Firefox 4 and Firefox 5. Bert Hubert and Theo Snelleman of Fox-IT reported a crash in the Ogg reader which affected Firefox 4 and Firefox 5.

Mozilla developers and community members reported memory safety issues which affected Firefox 4 and Firefox 5. 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. 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.

Michael Jordon of Context IS reported a potentially exploitable heap overflow in the ANGLE library used by Mozilla’s WebGL implementation. Security researcher regenrecht reported via TippingPoint’s Zero Day Initiative that a SVG text manipulation routine contained a dangling pointer vulnerability. 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. 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.

  * 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)
