This script is Copyright (C) 2010-2017 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-201006-16
(GD: User-assisted execution of arbitrary code)

Tomas Hoger reported that the _gdGetColors() function in gd_gd.c does
not properly verify the colorsTotal struct member, possibly leading to
a buffer overflow.

Impact :

A remote attacker could entice a user to open a specially crafted image
file with a program using the GD library, possibly resulting in the
remote execution of arbitrary code with the privileges of the user
running the application, or a Denial of Service condition.

Workaround :

There is no known workaround at this time.

Solution :

All GD users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/gd-2.0.35-r1'
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since November 21, 2009. It is likely that your system is
already no longer affected by this issue.
