Description

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.
