CVE-2018-18505 (GCVE-0-2018-18505)

Vulnerability from cvelistv5 – Published: 2019-02-05 21:00 – Updated: 2024-08-05 11:08

Summary

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.

Severity

No CVSS data available.

CWE

Privilege escalation through IPC channel messages

This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process.
