CVE-2006-1221: Zonelabs zonealarm security suite vulnerability
Zonelabs · Zonealarm Security Suite
Untrusted search path vulnerability in the TrueVector service (VSMON.exe) in Zone Labs ZoneAlarm 6.x and Integrity does not search ZoneAlarm's own folders before other folders that are specified in a user's PATH, which might allow local users to execute code as SYSTEM by placing malicious DLLs into a folder that has insecure permissions, but is searched before ZoneAlarm's folder. NOTE: since this issue is dependent on the existence of a vulnerability in a separate product (weak permissions of executables or libraries, or the execution of malicious code), perhaps it should not be included in CVE.
