CentOS 4 : tcpdump (CESA-2007:0387)

Medium Nessus Plugin ID 67051


The remote CentOS host is missing one or more security updates.


Updated tcpdump packages that fix a security issue and functionality bugs are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Tcpdump is a command line tool for monitoring network traffic.

Moritz Jodeit discovered a denial of service bug in the tcpdump IEEE 802.11 processing code. An attacker could inject a carefully crafted frame onto the IEEE 802.11 network that could crash a running tcpdump session if a certain link type was explicitly specified.

An integer overflow flaw was found in tcpdump's BGP processing code.
An attacker could execute arbitrary code with the privilege of the pcap user by injecting a crafted frame onto the network.

In addition, the following bugs have been addressed :

* if called with -C and -W switches, tcpdump would create the first savefile with the privileges of the user that executed tcpdump (usually root), rather than with ones of the pcap user. This could result in the inability to save the complete traffic log file properly without the immediate notice of the user running tcpdump.

* the arpwatch service initialization script would exit prematurely, returning a successful exit status incorrectly and preventing the status command from running in case networking is not available.

Users of tcpdump are advised to upgrade to these erratum packages, which contain backported patches that correct these issues.


Update the affected tcpdump packages.
