Comodo Firewall Pro SSDT() denial of service
| comodo-ssdt-dos (42082) |  Low Risk |
Description:
Comodo Firewall Pro is vulnerable to a denial of service, caused by improper validation of user-supplied input when handling arguments passed to the "NtDeleteFile()" "NtCreateFile()", and "NtSetThreadContext()" System Service Descriptor Table (SSDT) functions. By invoking these functions with specially-crafted arguments, a local attacker could exploit this vulnerability to cause a denial of service.
Platforms Affected:
- Comodo, Comodo Firewall Pro 2.4.18.184
Remedy:
Upgrade to the latest version of Comodo Firewall Pro (3.0 or later), available from the Comodo Firewall Pro Web site. See References.

- CVE-2008-1736: 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.
