3) Description of Vulnerability

Secunia Research has discovered a vulnerability in AhnLab V3 
Antivirus, which can be exploited by malicious people to compromise
a vulnerable system.

The vulnerability is caused due to a boundary error in the archive
decompression library when reading the filename of a compressed file 
from an ALZ, UUE or XXE archive. This can be exploited to cause a 
stack-based buffer overflow (ALZ), or a heap-based buffer overflow
(UUE/XXE), when a malicious ALZ/UUE/XXE archive is scanned.

Successful exploitation allows arbitrary code execution, but requires 
that compressed file scanning is enabled.

======================================================================

Update to version 6.0.0.488 via Smart Update.
