Date: August 09, 2007
Bugs: #179154
ID: 200708-05
Synopsis

Multiple vulnerabilities have been discovered in GD, allowing for the
execution of arbitrary code.
Background
=========
GD is a graphic library for fast image creation.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/gd < 2.0.35 >= 2.0.35
==========
Xavier Roche discovered an infinite loop in the gdPngReadData()
function when processing a truncated PNG file (CVE-2007-2756). An
integer overflow has been discovered in the gdImageCreateTrueColor()
function (CVE-2007-3472). An error has been discovered in the function

An error has been discovered when processing a GIF image that has no
global color map (CVE-2007-3475). An array index error has been
discovered in the file gd_gif_in.c when processing images with an
invalid color index (CVE-2007-3476). An error has been discovered in

discovered in the gdImageStringFTEx() function (CVE-2007-3478).
Impact
=====
A remote attacker could exploit one of these vulnerabilities to cause a
Denial of Service or possibly execute arbitrary code with the
privileges of the user running GD.
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"
