RHEL 2.1 : tcpdump (RHSA-2003:033)

high Nessus Plugin ID 12358

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated tcpdump, libpcap, and arpwatch packages are available to fix an incorrect bounds check when decoding BGP packets and a possible denial of service.

Tcpdump is a command-line tool for monitoring network traffic.

The BGP decoding routines in tcpdump before version 3.6.2 used incorrect bounds checking when copying data, which allows remote attackers to cause a denial of service and possibly execute arbitrary code (as the 'pcap' user).

If a UDP packet from a radius port contains 0 at the second byte tcpdump gets stuck in a loop that generating an infinite stream of '#0#0#0#0#0'. This could be used as a denial of service.

Users of tcpdump are advised to upgrade to these errata packages which contain patches to correct thes issues.

Solution

Update the affected arpwatch, libpcap and / or tcpdump packages.
