CVE-2008-1736: Comodo Personal Firewall

High severity, CVSS 7.2. EPSS: 0.4% chance of exploitation in the next 30 days.

Comodo Firewall Pro before 3.0 does not properly validate certain parameters to hooked System Service Descriptor Table (SSDT) functions, which allows local users to cause a denial of service (system crash) via (1) a crafted OBJECT_ATTRIBUTES structure in a call to the NtDeleteFile function, which leads to improper validation of a ZwQueryObject result; and unspecified calls to the (2) NtCreateFile and (3) NtSetThreadContext functions, different vectors than CVE-2007-0709.
