Fedora Legacy Update Advisory
Synopsis: Updated gd packages fix security issues
Advisory ID: FLSA:152838
Issue date: 2005-07-15
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CAN-2004-0941 CAN-2004-0990
- ---------------------------------------------------------------------
- ---------------------------------------------------------------------
1. Topic:
Updated gd packages that fix security issues with overflow in various
memory allocation calls are now available.
The gd packages contain a graphics library used for the dynamic creation
of images such as PNG and JPEG.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
3. Problem description:
Several buffer overflows were reported in various memory allocation
calls. An attacker could create a carefully crafted image file in such a
way that it could cause ImageMagick to execute arbitrary code when
processing the image. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0990 to these issues.
While researching the fixes to these overflows, additional buffer
overflows were discovered in calls to gdMalloc. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CAN-2004-0941 to these issues.
Users of gd should upgrade to these updated packages, which contain a
backported security patch, and are not vulnerable to these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which
are not installed but included in the list will not be updated. Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.
Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
