CVE-2017-7804

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 55 Firefox ESR versions prior to 52.3 Thunderbird versions prior to 52.3

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. The vulnerability is associated with insufficient input validation in the destructor function of the WindowsDllDetourPatcher class in Firefox, Firefox ESR, and Thunderbird browsers, allowing a remote attacker to potentially elevate their privileges.

Recommendations For Firefox versions prior to 55, update to version 55 or later. For Firefox ESR versions prior to 52.3, update to version 52.3 or later. For Thunderbird versions prior to 52.3, update to version 52.3 or later.
