|Gentoo Linux Security Advisory
Title: GD: User-assisted execution of arbitrary code (GLSA 201006-16)
Date: June 03, 2010
The GD library is prone to a buffer overflow vulnerability.
GD is a graphic library for fast image creation.
Vulnerable: < 2.0.35-r1
Unaffected: >= 2.0.35-r1
Architectures: All supported architectures
Tomas Hoger reported that the _gdGetColors() function in gd_gd.c does
not properly verify the colorsTotal struct member, possibly leading to
a buffer overflow.
A remote attacker could entice a user to open a specially crafted image
file with a program using the GD library, possibly resulting in the
remote execution of arbitrary code with the privileges of the user
running the application, or a Denial of Service condition.
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-r1"
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since November 21, 2009. It is likely that your system is
already no longer affected by this issue.
