AVG Scanning Engine UPX Parsing Denial of Service Vulnerability

High

Synopsis

The remote host is vulnerable to a flaw which allows malcode to be passed

Description

AVG Anti-Virus is installed on the remote Windows host. The version of AVG Anti-Virus installed on the remote host is affected by a flaw wherein remote attackers can bypass the scanning engine by sending specially formatted 'rar' and 'zip' archive files. An attacker, exploiting this flaw, would only need the ability to send email to valid recipients on the target server. Successful exploitation would result in the attacker being able to pass malware through the AVG server.

Solution

Upgrade to AVG 8.5 323 or later.
