Synopsis
========

Ethereal is vulnerable to numerous vulnerabilities, potentially
resulting in the execution of arbitrary code.

Background
==========

Ethereal is a feature-rich network protocol analyzer.

Affected packages
=================

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/ethereal      < 0.99.0                     >= 0.99.0

Description
===========

Coverity discovered numerous vulnerabilities in versions of Ethereal
prior to 0.99.0, including:

* buffer overflows in the ALCAP (CVE-2006-1934), COPS (CVE-2006-1935)
  and telnet (CVE-2006-1936) dissectors.

* buffer overflows in the NetXray/Windows Sniffer and Network
  Instruments file code (CVE-2006-1934).

For further details please consult the references below.

Impact
======

An attacker might be able to exploit these vulnerabilities to crash
Ethereal or execute arbitrary code with the permissions of the user
running Ethereal, which could be the root user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ethereal users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.99.0"
