## Description

Multiple untrusted search path vulnerabilities in updater.exe in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 on Windows, when the Maintenance Service is not used, allow local users to gain privileges via a Trojan horse DLL in (1) the current working directory or (2) a temporary directory, as demonstrated by bcrypt.dll.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
