Fedora Legacy Update Advisory
Synopsis: Updated CUPS packages fix security vulnerability
Advisory ID: FLSA:2072
Issue date: 2004-10-16
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2072
CVE Names: CAN-2004-0558
-----------------------------------------------------------------------
-----------------------------------------------------------------------
1. Topic:
Updated cups packages that fix a denial of service vulnerability are now available.
The Common UNIX Printing System (CUPS) is a print spooler.
2. Relevant releases/architectures:
Red Hat Linux 9 - i386
Fedora Core 1 - i386
3. Problem description:
Alvaro Martinez Echevarria reported a bug in the CUPS Internet Printing Protocol (IPP) implementation in versions of CUPS prior to 1.1.21. An attacker could send a carefully crafted UDP packet to the IPP port which could cause CUPS to stop listening to the port and result in a denial of service. In order to exploit this bug, an attacker would need to have the ability to send a UDP packet to the IPP port (by default 631). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0558 to this issue.
All users of cups should upgrade to these updated packages, which contain a backported patch as well as a fix for a non-exploitable off-by-one bug.
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.
