CVE-2022-22737

Name of the Vulnerable Software and Affected Versions Firefox ESR versions prior to 91.5 Firefox versions prior to 96 Thunderbird versions prior to 91.5

Description The issue is related to a use-after-free error due to a race condition when playing audio files and closing windows. This could lead to a potentially exploitable crash, allowing a remote attacker to create a specially crafted audio shell and execute arbitrary code in the system. The exploitation is tied to the construction of audio sinks and the concurrent closure of windows.

Recommendations For Firefox ESR versions prior to 91.5, update to version 91.5 or later. For Firefox versions prior to 96, update to version 96 or later. For Thunderbird versions prior to 91.5, update to version 91.5 or later.
