RHSA-2011:0370 - Security Advisory

Topic

Updated wireshark packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

Wireshark is a program for monitoring network traffic. Wireshark was
previously known as Ethereal.

A heap-based buffer overflow flaw was found in Wireshark. If Wireshark
opened a specially-crafted capture file, it could crash or, possibly,
execute arbitrary code as the user running Wireshark. (CVE-2011-0024)

Several denial of service flaws were found in Wireshark. Wireshark could
crash or stop responding if it read a malformed packet off a network, or
opened a malicious dump file. (CVE-2010-3445, CVE-2011-0538, CVE-2011-1139,
CVE-2011-1140, CVE-2011-1141, CVE-2011-1143)

Users of Wireshark should upgrade to these updated packages, which contain
backported patches to correct these issues. All running instances of
Wireshark must be restarted for the update to take effect.
