RHSA-2006:0156 - Security Advisory

Topic

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.

Description

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.
