Red Hat Security Advisory
Synopsis: Updated Pan packages fix denial of service vulnerability
Advisory ID: RHSA-2003:311-01
Issue date: 2003-11-24
Updated on: 2003-11-24
Product: Red Hat Linux
Keywords: DoS
Cross references:
Obsoletes:
CVE Names: CAN-2003-0855
- ---------------------------------------------------------------------
1. Topic:
Updated Pan packages that close a denial of service vulnerability are
now available.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386
3. Problem description:
Pan is a Gnome/GTK+ newsreader.
A bug in Pan versions prior to 0.13.4 can cause Pan to crash when
parsing an article header containing a very long author email
address. This bug causes a crash (denial of service) but is not
further exploitable. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2003-0855 to this
issue.
Users of Pan are advised to upgrade to these erratum packages, which
contain a backported patch correcting this issue.
Red Hat would like to thank Kasper Dupont for alerting us to this
issue and to Charles Kerr for providing the patch.
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 Red Hat Network.
Many people find this an easier way to apply updates. To use Red Hat
Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.
If up2date fails to connect to Red Hat Network due to SSL Certificate
Errors, you need to install a version of the up2date client with an
updated certificate. The latest version of up2date is available
from the Red Hat FTP site and may also be downloaded directly from
the RHN website:
https://rhn.redhat.com/help/latest-up2date.pxt
