Summary
Red Hat Security Advisory: : Updated tcpdump packages fix various vulnerabilities

Notes

Topic
Updated tcpdump, libpcap, and arpwatch packages are available, fixing a number of vulnerabilities that could be used to cause a denial of service attack, or possibly execute arbitrary code.
Details
tcpdump is a command-line tool for monitoring network traffic. The BGP decoding routines in tcpdump before 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). The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0. This causes tcpdump to generate data within an infinite loop. A vulnerability in tcpdump before 3.7.2 is related to an inability to handle unknown RADIUS attributes properly, and allows remote attackers to cause a denial of service (infinite loop). The ISAKMP parser in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a malformed ISAKMP packet to UDP port 500, causing tcpdump to enter an infinite loop. Users of tcpdump are advised to upgrade to these errata packages, which contain patches to correct these issues.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
