Ubuntu Security Notice 2151-1 - Benoit Jacob, Olli Pettay, Jan Varga, Jan de Mooij, Jesse Ruderman, Dan Gohman and Christoph Diehl discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. Atte Kettunen discovered an out-of-bounds read during WAV file decoding. If a user had enabled audio, an attacker could potentially exploit this to cause a denial of service via application crash. Various other issues were also addressed.
