Details

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.

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.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
