RHSA-2003-033: arpwatch Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the arpwatch packages
Detailed Explanation for this Vulnerability Test
Updated tcpdump, libpcap, and arpwatch packages are available to fix an
incorrect bounds check when decoding BGP packets and a possible denial of
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.
