DESCRIPTION:
Juan Pablo Lopez Yacubian has discovered a vulnerability in ZoneAlarm
Internet Security Suite, which can be exploited by malicious people to
compromise a user's system.

The vulnerability is caused due to a boundary error in multiscan.exe
when processing input from files passed via the "-f" command line
parameter. This can be exploited to cause a buffer overflow by e.g.
tricking a user into scanning a file or directory with a specially
crafted name via the "Scan with ZoneAlam Anti-virus" shell
extension.

Successful exploitation may allow the execution of arbitrary code.

The vulnerability is confirmed in version 7.0.483.000 and
8.0.020.000. Other versions may also be affected.

SOLUTION:
A solution is not available.
