User Rating:      How can I rate this item?
Posted by LinuxSecurity.com Team   
Fedora Both vulnerabilities will make the Ethereal application crash. The Q.931 vulnerability also affects Tethereal. It is not known if either vulnerability can be used to make Ethereal or Tethereal run arbitrary code.

---------------------------------------------------------------------
Fedora Update Notification
FEDORA-2003-040
2003-12-18
---------------------------------------------------------------------

Name        : ethereal
Version     : 0.10.0a
Release     : 0.1
Summary     : Network traffic analyzer
Description : 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 plugins and
documentation for ethereal. A graphical user interface is packaged
separately to GTK+ package.

---------------------------------------------------------------------
Update Information:

 Serious issues have been discovered in the following protocol dissectors:

    * Selecting "Match->Selected" or "Prepare->Selected" for a malformed SMB packet could cause a segmentation fault.
    * It is possible for the Q.931 dissector to dereference a null pointer when reading a malformed packet.

Impact:

Both vulnerabilities will make the Ethereal application crash. The Q.931 vulnerability also affects Tethereal. It is not known if either vulnerability can be used to make Ethereal or Tethereal run arbitrary code.

Resolution:

Upgrade to 0.10.0.

If you are running a version prior to 0.10.0 and you cannot upgrade, you can disable the SMB and Q.931 protocol dissectors by selecting Edit->Protocols... and deselecting them from the list.
