GENTOO LINUX SECURITY ANNOUNCEMENT 200311-04
---------------------------------------------------------------------------

GLSA: 200311-04
package: net-analyzer/ethereal
summary: Security problems in Ethereal 0.9.15
severity: normal
Gentoo bug: 32691
date: 2003-11-22
CVE: none
exploit: remote
affected: <0.9.16
fixed: >=0.9.16

DESCRIPTION:


Quote from <http://www.ethereal.com/appnotes/enpa-sa-00011.html>:

Potential security issues have been discovered in the following protocol
dissectors:

* An improperly formatted GTP MSISDN string could cause a buffer
overflow.

* A malformed ISAKMP or MEGACO packet could make Ethereal or
Tethereal crash.

* The SOCKS dissector was susceptible to a heap overlfow.

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 0.9.16.

If you are running a version prior to 0.9.16 and you cannot
upgrade, you can disable the GTP, ISAKMP, MEGACO, and SOCKS
protocol dissectors by selecting Edit->Protocols... and
deselecting them from the list.


SOLUTION:


It is recommended that all Gentoo Linux users who are running
net-analyzer/ethereal 0.9.x upgrade:

emerge sync
emerge '>=net-analyzer/ethereal-0.9.16'
emerge clean
