It was discovered that a buffer overflow in the ENTTEC dissector may lead to the execution of arbitrary code.

Wireshark was updated to version 1.4.4 to fix several security issues

The remote host is affected by the vulnerability described in GLSA-201110-02 (Wireshark: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Wireshark. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could send specially crafted packets on a network       being monitored by Wireshark, entice a user to open a malformed packet       trace file using Wireshark, or deploy a specially crafted Lua script for       use by Wireshark, possibly resulting in the execution of arbitrary code,       or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

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.

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.

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2011-03:01 advisory.

    Wireshark is a network traffic analyzer for Unix-ish operating systems.
    This package lays base for libpcap, a packet capture and filtering library, contains command-line     utilities, contains plugins and documentation for wireshark. A graphical user interface is packaged     separately to GTK+ package.
    Security issues fixed with this release:
    CVE-2010-4538     Buffer overflow in epan/dissectors/packet-enttec.c in Wireshark 1.4.2 allows remote attackers to cause a     denial of service (application crash) or possibly execute arbitrary code via a crafted ENTTEC DMX packet     with Run Length Encoding (RLE) compression.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
