CUPS security issue

When processing a request, the CUPS scheduler would use case-sensitive matching on the queue name to decide which authorization policy should be used. However, queue names are not case-sensitive. An unauthorized user could print to a password-protected queue without needing a password.

Fedora Legacy Update Advisory

Synopsis: Updated CUPS packages fix security issue
Advisory ID: FLSA:163274
Issue date: 2005-09-14
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CAN-2005-2154
---------------------------------------------------------------------


---------------------------------------------------------------------
1. Topic:

Updated CUPS packages that fix a security issue are now available.

The Common UNIX Printing System provides a portable printing layer for
UNIX(R) operating systems.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386

3. Problem description:

When processing a request, the CUPS scheduler would use case-sensitive
matching on the queue name to decide which authorization policy should
be used. However, queue names are not case-sensitive. An unauthorized
user could print to a password-protected queue without needing a
password. The Common Vulnerabilities and Exposures project has assigned
the name CAN-2005-2154 to this issue.

All users of CUPS should upgrade to these erratum packages which contain
a backported patch to correct 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.

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.
