Name of the Vulnerable Software and Affected Versions Firefox versions prior to 74

Description The issue is related to memory safety and script safety bugs in Firefox, which could potentially lead to memory corruption or escalation of privilege. It is presumed that with sufficient effort, some of these bugs could be exploited to run arbitrary code. The vulnerability is also described as a buffer overflow in memory, which could allow a remote attacker to execute arbitrary code.

Recommendations For versions prior to 74, update to version 74 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive resources until the update is applied.
