ClamAV < 0.95.2 Multiple Scan Evasion Vulnerabilities

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

The remote antivirus service is vulnerable to a file scan evasion
attack.

Description :

According to its version, the clamd antivirus daemon on the remote
host is earlier than 0.95.2. Such versions are reportedly affected by
multiple scan evasion vulnerabilities :

- An attacker could bypass antivirus detection by
embedding malicious code in a specially crafted 'CAB',
'RAR', or 'ZIP' archive.

- Due to an issue in 'libclamav/mbox.c', an attacker can
bypass antivirus detection by sending a UTF-16 encoded
email.

- Due to an issue in 'libclamav/readdb.c', certain
signatures that should be rejected are able to bypass
detection.
