Multiple personal firewall products are prone to a vulnerability that lets attackers bypass protection mechanisms. This issue occurs because the applications fail to properly implement protection mechanisms based on valid process identifiers.
Exploiting this issue allows local attackers to bypass protection mechanisms implemented to restrict access to the memory space of critical processes. This allows attackers to execute arbitrary code with elevated privileges; other attacks are also possible.
The following applications are vulnerable to this issue:
- Comodo Firewall Pro 184.108.40.206
- Comodo Personal Firewall 220.127.116.11
- ZoneAlarm Pro 6.1.744.001
Other applications and versions may also be affected.
