This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200511-04
(ClamAV: Multiple vulnerabilities)

ClamAV has multiple security flaws: a boundary check was performed
incorrectly in petite.c, a buffer size calculation in unfsg_133 was
incorrect in fsg.c, a possible infinite loop was fixed in tnef.c and a
possible infinite loop in cabd_find was fixed in cabd.c . In addition
to this, Marcin Owsiany reported that a corrupted DOC file causes a
segmentation fault in ClamAV.

Impact :

By sending a malicious attachment to a mail server that is hooked with
ClamAV, a remote attacker could cause a Denial of Service or the
execution of arbitrary code.

Workaround :

There is no known workaround at this time.
