Description

Updated tcpdump packages are available to fix a denial of service vulnerability in tcpdump. [Updated 12 March 2003] Added packages for CentOS Linux ES and CentOS Linux WS

Tcpdump is a command-line tool for monitoring network traffic. The ISAKMP parser in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop. Users of tcpdump are advised to upgrade to these errata packages which contain a patch to correct this issue.
