RHSA-2007:0709 - Security Advisory

Topic

New Wireshark packages that fix various security vulnerabilities and
functionality bugs are now available for Red Hat Enterprise Linux 4.
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)

Wireshark would interpret certain completion codes incorrectly when
dissecting IPMI traffic. Additionally, IPMI 2.0 packets would be reported
as malformed IPMI traffic.

Users of Wireshark should upgrade to these updated packages containing
Wireshark version 0.99.6, which correct these issues.
