## Description

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before 2.12 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to garbage collection after certain MethodJIT execution, and unknown other vectors.

## What to do
