Ubuntu Security Notice USN-1210-1

Ubuntu Security Notice 1210-1 – Benjamin Smedberg, Bob Clary, Jesse Ruderman, and Josh Aas discovered multiple memory vulnerabilities in the browser rendering engine. An attacker could use these to possibly execute arbitrary code with the privileges of the user invoking Firefox. Boris Zbarsky discovered that a frame named « location » could shadow the window.location object unless a script in a page grabbed a reference to the true object before the frame was created. This is in violation of the Same Origin Policy. A malicious website could possibly use this to access another website or the local file system. Various other issues were also addressed.
