Memory safety fixes in liboggplay media library

December 15, 2009
Mozilla community and developers
Firefox, SeaMonkey, Thunderbird
Fixed in
  • Firefox 3.5.6
  • SeaMonkey 2.0.1
  • Thunderbird 3.0.1


Mozilla discovered several bugs in liboggplay which posed potential memory safety issues. The bugs which were fixed could potentially be used by an attacker to crash a victim's browser and execute arbitrary code on their computer.

Audio and Video capabilities were added to the Mozilla browser engine in Firefox 3.5, SeaMonkey 2.0, and Thunderbird 3.0; prior releases of these products were not affected.


David Keeler and Bob Clary reported crashes in liboggplay.
