Fedora Legacy Update Advisory
Synopsis: Updated gdk-pixbuf packages fix security flaws
Advisory ID: FLSA:2005
Issue date: 2005-02-23
Product: Red Hat Linux
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2005
CVE Names: CAN-2004-0111 CAN-2004-0753 CAN-2004-0782
CAN-2004-0783 CAN-2004-0788

1. Topic:
Updated gdk-pixbuf packages that fix several security flaws are now available.
The gdk-pixbuf package contains an image loading library used with the GNOME GUI desktop environment.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
3. Problem description:
Thomas Kristensen discovered a bitmap file that would cause the Evolution mail reader to crash. This issue was caused by a flaw that affects versions of the gdk-pixbuf package prior to 0.20. To exploit this flaw, a remote attacker could send (via email) a carefully-crafted BMP file, which would cause Evolution to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0111 to this issue.
During testing of a previously fixed flaw in Qt (CAN-2004-0691), a flaw was discovered in the BMP image processor of gdk-pixbuf. An attacker could create a carefully crafted BMP file which would cause an application to enter an infinite loop and not respond to user input when the file was opened by a victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0753 to this issue.
During a security audit, Chris Evans discovered a stack and a heap overflow in the XPM image decoder. An attacker could create a carefully crafted XPM file which could cause an application linked with gtk2 to crash or possibly execute arbitrary code when the file was opened by a victim. (CAN-2004-0782, CAN-2004-0783)
Chris Evans also discovered an integer overflow in the ICO image decoder. An attacker could create a carefully crafted ICO file which could cause an application linked with gtk2 to crash when the file is opened by a victim. (CAN-2004-0788)
Users of gdk-pixbuf are advised to upgrade to these packages, which contain backported patches 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.

Fedora Legacy Update Advisory
Synopsis: Updated zlib package fixes security issues
Advisory ID: FLSA:2043
Issue date: 2005-02-23
Product: Fedora Core
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2043
CVE Names: CAN-2004-0797
- ---------------------------------------------------------------------
- ---------------------------------------------------------------------
1. Topic:
An updated zlib package that fixes a security flaw is now available.
Zlib is a general-purpose, patent-free, lossless data compression library which is used by many different programs.
2. Relevant releases/architectures:
Fedora Core 1 - i386
3. Problem description:
Johan Thelmen reported that a specially crafted file can cause a segmentation fault in zlib as the inflate() and inflateBack() functions do not properly handle errors. An attacker could construct a carefully crafted file that could cause a crash or possibly execute arbitrary code when opened. The specific impact depends on the application using zlib. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0797 to this issue.
Users of zlib are advised to upgrade to this errata package, which contains a backported patch correcting this issue.
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.
