Summary
Red Hat Security Advisory: : Updated tcpdump packages fix buffer overflow
Notes
Topic
Updated tcpdump, libpcap, and arpwatch packages are available for Red
Hat Linux 6.2 and 7.x. These updates close a buffer overflow when handling
NFS packets.
[Update 3 October 2002]
Replacement packages have been added for Red Hat Linux 6.2 as the previous
packages could not be installed with the version of RPM that shipped with
Red Hat Linux 6.2. Replacement packages have also been added for Red Hat
Linux 7.0 as the previous packages were not built correctly.
Details
tcpdump is a command-line tool for monitoring network traffic. Versions of
tcpdump up to and including 3.6.2 have a buffer overflow that can be
triggered when tracing the network by a bad NFS packet.
We are not yet aware if this issue is fully exploitable; however, users of
tcpdump are advised to upgrade to these errata packages which contain a
patch for this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0380 to this issue. This issue was found by
David Woodhouse of Red Hat.

Only those\nRPMs which are currently installed will be updated. Those RPMs which are\nnot installed but included in the list will not be updated. Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network. Many\npeople find this an easier way to apply updates. To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
