The host is installed with Mozilla Firefox 4.x through 13.0, Firefox ESR 10.x before 10.0.6, Thunderbird 5.0 through 13.0, Thunderbird ESR 10.x before 10.0.6, or SeaMonkey before 2.11 and is prone to multiple vulnerabilities. The flaws are present in the applications, which fail to properly handle vectors involving multiple adoptions and empty documents. Successful exploitation could remote attackers to cause a denial of service (buffer over-read, incorrect pointer dereference, and heap-based buffer overflow) or possibly execute arbitrary code.
