Severity:	normal
Title:	GD: Multiple vulnerabilities
Date:	08/09/2007
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	Architecture(s)
media-libs/gd	< 2.0.35	>= 2.0.35	All supported architectures

Description

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 gdImageCreateXbm() function (CVE-2007-3473). Unspecified vulnerabilities have been discovered in the GIF reader (CVE-2007-3474). 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 the imagearc() and imagefilledarc() functions when processing overly large angle values (CVE-2007-3477). A race condition has been 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"
