๐จ **Essence**: A **Copy-on-Write (COW)** bypass vulnerability in Mozilla products. ๐ **Consequences**: Allows **Privilege Escalation**.โฆ
๐ก๏ธ **Root Cause**: The flaw lies in the **Copy-on-Write mechanism**. ๐ **Flaw**: The implementation fails to properly handle memory isolation during the COW process, allowing a bypass of security boundaries.โฆ
๐ฆ **Affected Software**: Mozilla Firefox, Thunderbird, and SeaMonkey. ๐ **Versions**: Firefox **< 18.0** and Firefox ESR **< 17.0**. All other versions are potentially safe.
Q4What can hackers do? (Privileges/Data)
