Name of the Vulnerable Software and Affected Versions
Mozilla Firefox versions prior to 121
Description
The issue is related to inadequate exception handling in Mozilla Firefox, which can be exploited by a remote attacker to cause a denial of service. Specifically,
TypedArrays can be fallible and lack proper exception handling, potentially leading to abuse in other APIs that expect TypedArrays to always succeed.Recommendations
For versions prior to 121, update to version 121 or later to resolve the issue. As a temporary workaround, consider restricting the use of
TypedArrays in affected APIs until a patch is available.Exploit
