Fedora Core 1 : ethereal-0.10.5-0.1.1 (2004-219)

Medium Nessus Plugin ID 13738


The remote Fedora Core host is missing a security update.


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

Impact :

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.

Resolution :

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 0.10.5.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected ethereal, ethereal-debuginfo and / or ethereal-gnome packages.
