Title: GD: Multiple vulnerabilities (GLSA 200708-05)
Date: August 09, 2007
Multiple vulnerabilities have been discovered in GD, allowing for the
execution of arbitrary code.
GD is a graphic library for fast image creation.
Vulnerable: < 2.0.35
Unaffected: >= 2.0.35
Architectures: All supported architectures
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).
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.
There is no known workaround at this time.
All GD users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.35"
