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 < 0.10.13-r1 >= 0.10.13-r1
Description
===========
There are numerous vulnerabilities in versions of Ethereal prior to
0.10.13, including:
* The SLIM3 and AgentX dissectors could overflow a buffer
(CVE-2005-3243).
* iDEFENSE discovered a buffer overflow in the SRVLOC dissector
(CVE-2005-3184).
* Multiple potential crashes in many dissectors have been fixed, see
References for further details.
Furthermore an infinite loop was discovered in the IRC protocol
dissector of the 0.10.13 release (CVE-2005-3313).
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-0.10.13-r1"
