Gentoo Linux Security Advisory

Title: GD: Integer overflow (GLSA 200411-08)
Severity: normal
Exploitable: remote
Date: November 03, 2004
Bug(s): #69070
ID: 200411-08

Synopsis

The PNG image decoding routines in the GD library contain an integer overflow that may allow execution of arbitrary code with the rights of the program decoding a malicious PNG image.

Background

The GD graphics library is an open source library which allows programmers to easily generate PNG, JPEG, GIF and WBMP images from many different programming languages.

Affected Packages

Package: media-libs/gd
Vulnerable: < 2.0.32
Unaffected: >= 2.0.32
Architectures: All supported architectures


Description

infamous41md found an integer overflow in the memory allocation procedure of the GD routine that handles loading PNG image files.

Impact

A remote attacker could entice a user to load a carefully crafted PNG image file in a GD-powered application, or send a PNG image to a web application which uses GD PNG decoding functions. This could potentially lead to execution of arbitrary code with the rights of the program loading the image.

Workaround

There is no known workaround at this time.

Resolution

All GD users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.32"
