Name of the Vulnerable Software and Affected Versions Firefox versions prior to 78

Description The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. It is also described as a buffer data boundary operation issue, where exploitation could allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations For versions prior to 78, update to version 78 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive data and implementing additional security measures to minimize the risk of exploitation.
