RHSA-2005:505 - Security Advisory

Topic

Updated tcpdump packages that fix a security issue are now available.

This update has been rated as having low security impact by the Red
Hat Security Response Team.

Description

Tcpdump is a command line tool for monitoring network traffic.

A denial of service bug was found in tcpdump during the processing of
certain network packets. It is possible for an attacker to inject a
carefully crafted packet onto the network, crashing a running tcpdump
session. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2005-1267 to this issue.

Users of tcpdump are advised to upgrade to these erratum packages, which
contain backported security patches and are not vulnerable to these issues.
