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.

(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.
