NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox-esr package and not the firefox-esr package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

In some cases, an untrusted input stream was copied to a stack buffer without checking its size. This resulted in a potentially exploitable crash which could have led to a sandbox escape. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1.
