Firefox ESR is vulnerable to Denial Of Service (DoS). The vulnerability occurs if Windows does not duplicate a handle during process creation. In such cases, the sandbox code may unintentionally free a pointer twice, leading to a use-after-free situation and a potentially exploitable crash. This bug only affects Firefox on Windows when run in non-standard configurations (such as using runas).
