GENTOO LINUX SECURITY ANNOUNCEMENT

PACKAGE        :ethereal
SUMMARY        :buffer overflow
DATE           :2002-08-30 07:30 UTC

- - --------------------------------------------------------------------

OVERVIEW

The ISIS protocol dissector in Ethereal 0.9.5 and earlier versions
is susceptible to a buffer overflow.

DETAIL

It may be possible to make Ethereal crash or hang by injecting a
purposefully malformed packet onto the wire, or by convincing someone
to read a malformed packet trace file. It may be possible to make
Ethereal run arbitrary code by exploiting the buffer and pointer problems.

The full advisory can be read at
http://www.ethereal.com/appnotes/enpa-sa-00006.html

SOLUTION

It is recommended that all Gentoo Linux users who are running
net-analyzer/ethereal-0.9.5-r2 and earlier update their systems
as follows:

emerge rsync
emerge ethereal
emerge clean
