Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 55

Description
The issue is related to the destructor function for the WindowsDllDetourPatcher class, which can be exploited by malicious code to write arbitrary data to a controlled location in memory. This can bypass existing memory protections. The attack is limited to Windows operating systems.
