Microsoft Windows XP and Windows Server 2003 do not properly handle user logoff, which might allow local users to gain the privileges of a previous system user, possibly related to user profile unload failure. NOTE: it is not clear whether this is an issue in Windows itself, or an interaction with another product. The issue might involve ZoneAlarm not being able to terminate processes when it cannot prompt the user.
Integer overflow in Computer Associates Vet Antivirus library, as used by CA InoculateIT 6.0, eTrust Antivirus r6.0 through 7.1, eTrust Antivirus for the Gateway r7.0 and r7.1, eTrust Secure Content Manager, eTrust Intrusion Detection, BrightStor ARCserve Backup (BAB) r11.1, Vet Antivirus, Zonelabs ZoneAlarm Security Suite, and ZoneAlarm Antivirus, allows remote attackers to gain privileges via a compressed VBA directory with a project name length of -1, which leads to a heap-based buffer overflow.
Zone Alarm Pro 1.0 through 5.1 gives full access to %windir%\Internet Logs\* to the EVERYONE group, which allows local users to cause a denial of service by modifying the folder contents or permissions. NOTE: this issue has been disputed by the vendor, who claims that it does not affect product functionality since the same information is also saved in a protected file
ZoneAlarm and ZoneAlarm Pro allows a local attacker to cause a denial of service by running a trojan to initialize a ZoneAlarm mutex object which prevents ZoneAlarm from starting.
