Vulnerability Assessment Details
Check for the version of the ethereal package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory FEDORA-2004-220 (ethereal).
Ethereal is a network traffic analyzer for Unix-ish operating systems.
This package lays base for libpcap, a packet capture and filtering
library, contains command-line utilities, contains tests and
documentation for ethereal. A graphical user interface is packaged
separately to GTK+ package.
Issues have been discovered in the following protocol dissectors:
* The iSNS dissector could make Ethereal abort in some cases.
(0.10.3 - 0.10.4) CVE-2004-0633
* SMB SID snooping could crash if there was no policy name for a
handle. (0.9.15 - 0.10.4) CVE-2004-0634
* The SNMP dissector could crash due to a malformed or missing
community string. (0.8.15 - 0.10.4) CVE-2004-0635
It may be possible to make Ethereal crash or run arbitrary code by
injecting a purposefully malformed packet onto the wire or by convincing
someone to read a malformed packet trace file.
Upgrade to 0.10.5.
If you are running a version prior to 0.10.5 and you cannot upgrade, you
can disable all of the protocol dissectors listed above by selecting
Analyze->Enabled Protocols... and deselecting them from the list. For
SMB, you can alternatively disable SID snooping in the SMB protocol
preferences. However, it is strongly recommended that you upgrade to
