Multiple Vulnerabilities in Mozilla Products Could Allow for Arbitrary Code Execution

**Multiple vulnerabilities in Mozilla products (Firefox, Thunderbird, ESR)** have been disclosed, including several high-severity issues such as privilege escalation, use‑after‑free, sandbox escapes, JIT miscompilation, and other memory-safety bugs (multiple CVEs listed). Successful exploitation of the most severe flaws could allow arbitrary code execution, enabling attackers to install programs, access or delete data, or create accounts; impact depends on user privileges, and the advisory does not report active exploitation.
