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"
