CVE-2024-29944

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 124.0.1 Firefox ESR versions prior to 115.9.1

Description An attacker was able to inject an event handler into a privileged object that would allow arbitrary JavaScript execution in the parent process. This issue affects Desktop Firefox only and does not affect mobile versions of Firefox. The vulnerability is related to incorrect event handling due to improper code generation management. Exploitation of the vulnerability may allow a remote attacker to elevate their privileges and execute arbitrary code.

Recommendations For Firefox versions prior to 124.0.1, update to version 124.0.1 or later. For Firefox ESR versions prior to 115.9.1, update to version 115.9.1 or later. As a temporary workaround, consider disabling the execution of JavaScript in the parent process until a patch is available. Restrict access to privileged objects to minimize the risk of exploitation. Avoid using event handlers in the affected Firefox versions until the issue is resolved.
