Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 4.x through 8.0, Thunderbird 5.0 through 8.0, and SeaMonkey before 2.6 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors that trigger a compartment mismatch associated with the nsDOMMessageEvent::GetData function, and unknown other vectors.
