Gentoo Linux Security Advisory

Title: GD: Multiple vulnerabilities (GLSA 200708-05)
Severity: normal
Exploitable: remote
Date: August 09, 2007
Bug(s): #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: media-libs/gd
Vulnerable: < 2.0.35
Unaffected: >= 2.0.35
Architectures: 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.35"
