RHSA-2006:0602 - Security Advisory

Topic

New Wireshark packages that fix various security vulnerabilities in
Ethereal 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.

In May 2006, Ethereal changed its name to Wireshark. This update
deprecates the Ethereal packages in Red Hat Enterprise Linux 2.1, 3, and 4
in favor of the supported Wireshark packages.

Several denial of service bugs were found in Ethereal's protocol
dissectors. It was possible for Ethereal to crash or stop responding if it
read a malformed packet off the network. (CVE-2006-3627, CVE-2006-3629,
CVE-2006-3631)

Several buffer overflow bugs were found in Ethereal's ANSI MAP, NCP NMAS,
and NDPStelnet dissectors. It was possible for Ethereal to crash or execute
arbitrary code if it read a malformed packet off the network.
(CVE-2006-3630, CVE-2006-3632)

Several format string bugs were found in Ethereal's Checkpoint FW-1, MQ,
XML, and NTP dissectors. It was possible for Ethereal to crash or execute
arbitrary code if it read a malformed packet off the network. (CVE-2006-3628)

Users of Ethereal should upgrade to these updated packages containing
Wireshark version 0.99.2, which is not vulnerable to these issues
