CVE-2018-18505 (opens in a new tab)How to fix?
Upgrade Ubuntu:21.04 firefox to version 65.0+build2-0ubuntu1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Ubuntu.
See How to fix? for Ubuntu:21.04 relevant fixed versions and status.
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.
