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