Synopsis
========

Ethereal is vulnerable to numerous vulnerabilities potentially
resulting in the execution of arbitrary code or abnormal termination.

Background
==========

Ethereal is a feature-rich network protocol analyzer.

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

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/ethereal      < 0.10.12                   >= 0.10.12

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

There are numerous vulnerabilities in versions of Ethereal prior to
0.10.12, including:

* The SMB dissector could overflow a buffer or exhaust memory
  (CAN-2005-2365).

* iDEFENSE discovered that several dissectors are vulnerable to
  format string overflows (CAN-2005-2367).

* Additionally multiple potential crashes in many dissectors have
  been fixed, see References for further details.

Impact
======

An attacker might be able to use 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-0.10.12"
