Synopsis
=======

Multiple vulnerabilities exist in Ethereal, which may allow an attacker to run arbitrary code or crash the program.



Background
=========

Ethereal is a feature rich network protocol analyzer.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/ethereal < 0.10.10 >= 0.10.10

Description
==========

There are multiple vulnerabilities in versions of Ethereal earlier than 0.10.10, including:

* The Etheric and 3GPP2 A11 dissectors are vulnerable to buffer overflows (CAN-2005-0704 and CAN-2005-0699).

* The GPRS-LLC could crash when the "ignore cipher bit" option is enabled (CAN-2005-0705).

* Various vulnerabilities in the IAPP, JXTA, and sFlow dissectors.

Impact
=====

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

Workaround
=========

For a temporary workaround you can disable all affected protocol dissectors. However, it is strongly recommended that you upgrade to the latest stable version.

Resolution
=========

All Ethereal users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.10"
