CVE-2024-4775

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 126

Description The issue is related to a missing iterator stop condition when handling WASM code in the built-in profiler. This could lead to invalid memory access and undefined behavior, potentially allowing an attacker to access confidential data, compromise its integrity, and cause a denial of service. The issue only affects the application when the profiler is running.

Recommendations For versions prior to 126, update to version 126 or later to resolve the issue. As a temporary workaround, consider disabling the profiler until a patch is available.
