"Updated Ethereal packages that fix various security vulnerabilities
are now available.

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

Ethereal is a program for monitoring network traffic.

Two denial of service bugs were found in Ethereal's IRC and GTP
protocol dissectors. Ethereal could crash or stop responding if it
reads a malformed IRC or GTP packet off the network. The Common
Vulnerabilities and Exposures project (cve.mitre.org) assigned the
names CVE-2005-3313 and CVE-2005-4585 to these issues.

A buffer overflow bug was found in Ethereal's OSPF protocol dissector.
Ethereal could crash or execute arbitrary code if it reads a malformed
OSPF packet off the network. (CVE-2005-3651)

Users of ethereal should upgrade to these updated packages containing
version 0.10.14, which is not vulnerable to these issues."
