Synopsis
========

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

Background

    -------------------------------------------------------------------
     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

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
