"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.

Several denial of service bugs were found in Ethereal's protocol
dissectors. Ethereal could crash or stop responding if it reads a
malformed packet off the network. (CVE-2006-1932, CVE-2006-1933,
CVE-2006-1937, CVE-2006-1938, CVE-2006-1939, CVE-2006-1940)

Several buffer overflow bugs were found in Ethereal's COPS, telnet,
and ALCAP dissectors as well as Network Instruments file code and
NetXray/Windows Sniffer file code. Ethereal could crash or execute
arbitrary code if it reads a malformed packet off the network.
(CVE-2006-1934, CVE-2006-1935, CVE-2006-1936)

Users of ethereal should upgrade to these updated packages containing
version 0.99.0, which is not vulnerable to these issues."
