Security Advisory tcpdump security update

Advisory: RHSA-2005:421-04
Type: Security Advisory
Severity: Moderate
Issued on: 2005-05-11
Last updated on: 2005-05-11
Affected Products: Red Hat Desktop (v. 3)
Red Hat Enterprise Linux AS (v. 3)
Red Hat Enterprise Linux ES (v. 3)
Red Hat Enterprise Linux WS (v. 3)
CVEs (cve.mitre.org): CVE-2005-1278
CVE-2005-1279
CVE-2005-1280

Details

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.

These updated packages also add support for output files larger than 2 GB,
add support for some new VLAN IDs, and fix message parsing on 64bit
architectures.

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.

Additionally, the tcpdump utility can now write a file larger than 2 GB,
parse some new VLAN IDs, and parse messages on 64bit architectures.

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


Solution
