Synopsis
========
Multiple vulnerabilities exist in Ethereal, which may allow
an attacker to run arbitrary code, crash the program or
perform DoS by CPU and disk utilization.
Background
==========
Ethereal is a feature rich network protocol analyzer.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/ethereal < 0.10.8 >= 0.10.8
Description
===========
There are multiple vulnerabilities in versions of Ethereal
earlier than 0.10.8, including:
* Bug in DICOM dissection discovered by Bing could make Ethereal
crash (CAN 2004-1139).
* An invalid RTP timestamp could make Ethereal hang and create a
large temporary file (CAN 2004-1140).
* The HTTP dissector could access previously-freed memory (CAN
2004-1141).
* Brian Caswell discovered that an improperly formatted SMB could
make Ethereal hang (CAN 2004-1142).
Impact
======
An attacker might be able to use these vulnerabilities to
crash Ethereal, perform DoS by CPU and disk space utilization
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 version.
Resolution
==========
All ethereal users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=net-analyzer/ethereal-0.10.8"
