Synopsis

Moderate: wireshark security update

Type/Severity

Security Advisory Moderate

Topic

Updated wireshark packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

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

An array index error, leading to a stack-based buffer overflow, was found in the Wireshark ENTTEC dissector. If Wireshark read a malformed packet off a network or opened a malicious dump file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. (CVE-2010-4538)

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