                   Red Hat Security Advisory

Synopsis:          Updated CUPS packages fix security vulnerability
Advisory ID:       RHSA-2004:449-01
Issue date:        2004-09-15
Updated on:        2004-09-15
Product:           Red Hat Enterprise Linux
Keywords:          DoS
CVE Names:         CAN-2004-0558
- ---------------------------------------------------------------------

1. Summary:

Updated cups packages that fix a denial of service vulnerability are now
available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, ppc64, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

The Common UNIX Printing System (CUPS) is a print spooler.

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 that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

following Web page for the System Administration or Customization
guide specific to your system:
