CVE-2022-45406

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 107 Firefox ESR versions prior to 102.5 Thunderbird versions prior to 102.5

Description The issue is related to the use of memory after it has been freed when processing JavaScript code, potentially leading to a crash that could be exploited by a remote attacker. This could occur if an out-of-memory condition happens when creating a JavaScript global, causing a JavaScript realm to be deleted while references to it still exist in a BaseShape, resulting in a use-after-free situation.

Recommendations For Firefox versions prior to 107, update to version 107 or later to resolve the issue. For Firefox ESR versions prior to 102.5, update to version 102.5 or later to resolve the issue. For Thunderbird versions prior to 102.5, update to version 102.5 or later to resolve the issue.
