From bugzilla@redhat.com Wed Nov 26 04:16:05 2003 From: bugzilla@redhat.com To: redhat-watch-list@redhat.com, bugtraq@securityfocus.com, full-disclosure@lists.netsys.com Date: Mon, 24 Nov 2003 03:53 -0500 Subject: [Full-Disclosure] [RHSA-2003:311-01] Updated Pan packages fix denial of service vulnerability -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- 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 5.
