Topic

New Wireshark packages that fix various security vulnerabilities are now
available for Red Hat Enterprise Linux 5. Wireshark was previously known
as Ethereal.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

Wireshark is a program for monitoring network traffic.

Several denial of service bugs were found in Wireshark's HTTP, iSeries, DCP
ETSI, SSL, MMS, DHCP and BOOTP protocol dissectors. It was possible for
Wireshark to crash or stop responding if it read a malformed packet off the
network. (CVE-2007-3389, CVE-2007-3390, CVE-2007-3391, CVE-2007-3392,
CVE-2007-3393)

Users of Wireshark and Ethereal should upgrade to these updated packages,
containing Wireshark version 0.99.6, which is not vulnerable to these
issues.
