tcpdump security update
Security Advisory: Moderate
Updated tcpdump packages that fix several security issues are now available.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
This updated package also adds support for output files larger than 2 GB.
Tcpdump is a command-line tool for monitoring network traffic.
Several denial of service bugs were found in the way tcpdump processes
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 names CAN-2005-1278, CAN-2005-1279, and CAN-2005-1280 to
these issues.
The tcpdump utility can now write a file larger than 2 GB.
Users of tcpdump are advised to upgrade to these erratum packages, which
contain backported security patches and are not vulnerable to these issues.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
