Severity: Normal
Title: GD: User-assisted execution of arbitrary code
Date: June 03, 2010
Bugs: #292130
ID: 201006-16
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
=======
The GD library is prone to a buffer overflow vulnerability.
Background
=========
GD is a graphic library for fast image creation.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/gd < 2.0.35-r1 >= 2.0.35-r1
Description
==========
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.
Resolution
=========
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.
