1. Topic:
Updated tcpdump, libpcap, and arpwatch packages fix vulnerabilities in
ISAKMP and RADIUS parsing.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:
Tcpdump is a command-line tool for monitoring network traffic.
George Bakos discovered flaws in the ISAKMP decoding routines of tcpdump
versions prior to 3.8.1. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0989 to this issue.
Jonathan Heusser discovered an additional flaw in the ISAKMP decoding
routines for tcpdump 3.8.1 and earlier. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0057 to
this issue.
Jonathan Heusser discovered a flaw in the print_attr_string function in the
RADIUS decoding routines for tcpdump 3.8.1 and earlier. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0055 to this issue.
Remote attackers could potentially exploit these issues by sending
carefully-crafted packets to a victim. If the victim uses tcpdump, these
pakets could result in a denial of service, or possibly execute arbitrary
code as the 'pcap' user.
Users of tcpdump are advised to upgrade to these erratum packages, which
contain backported security patches and are not vulnerable to these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
Please note that this update is available via Red Hat Network. 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.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
113008 - CAN-2003-0989 tcpdump parsing overflow
113366 - CAN-2004-0055 CAN-2004-0057 Two issues found in tpcdump
