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"
