Synopsis
========

A bug in Zebedee allows a remote attacker to perform a Denial of
Service attack.

Background
==========

Zebedee is an application that establishes an encrypted, compressed
tunnel for TCP/IP or UDP data transfer between two systems.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-misc/zebedee       < 2.5.3                       *>= 2.4.1-r1
                                                              >= 2.5.3

Description
===========

"Shiraishi.M" reported that Zebedee crashes when "0" is received as the
port number in the protocol option header.

Impact
======

By performing malformed requests a remote attacker could cause Zebedee
to crash.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Zebedee users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose net-misc/zebedee
