Synopsis
========
Multiple vulnerabilities including one buffer overflow 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 <= 0.10.3 >= 0.10.4
Description
===========
There are multiple vulnerabilities in versions of Ethereal earlier than
0.10.4, including:
* A buffer overflow in the MMSE dissector.
* Under specific conditions a SIP packet could make Ethereal crash.
* The AIM dissector could throw an assertion, causing Ethereal to
crash.
* The SPNEGO dissector could dereference a null pointer, causing a
crash.
Impact
======
An attacker could use these vulnerabilities to crash Ethereal or even
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 by selecting Analyze->Enabled Protocols... and deselecting
them from the list. However, it is strongly recommended to upgrade to
the latest stable release.
Resolution
==========
All Ethereal users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-analyzer/ethereal-0.10.4"
# emerge ">=net-analyzer/ethereal-0.10.4"
