CVE-2018-18505

Priority
Description
An earlier fix for an Inter-process Communication (IPC) vulnerability,
CVE-2011-3079, added authentication to communication between IPC endpoints
and server parents during IPC process creation. This authentication is
insufficient for channels created after the IPC process is started, leading
to the authentication not being correctly applied to later channels. This
could allow for a sandbox escape through IPC channels due to lack of
message validation in the listener process. This vulnerability affects
Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
