CVE-2018-18505

Name of the Vulnerable Software and Affected Versions Thunderbird versions prior to 60.5 Firefox ESR versions prior to 60.5 Firefox versions prior to 65

Description The issue is related to an Inter-process Communication (IPC) vulnerability. It affects the authentication mechanism between IPC endpoints and server parents during IPC process creation. The authentication is insufficient for channels created after the IPC process is started, which could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process.

Recommendations For Thunderbird versions prior to 60.5, update to version 60.5 or later. For Firefox ESR versions prior to 60.5, update to version 60.5 or later. For Firefox versions prior to 65, update to version 65 or later.
