Synopsis
========

Multiple buffer overflow vulnerabilities in Heimdal's telnetd server
could allow the execution of arbitrary code.

Background
==========

Heimdal is a free implementation of Kerberos 5 that includes a telnetd
server.

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected

  1  app-crypt/heimdal       < 0.6.5                          >= 0.6.5

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

It has been reported that the "getterminaltype" function of Heimdal's
telnetd server is vulnerable to buffer overflows.

Impact
======

An attacker could exploit this vulnerability to execute arbitrary code
with the permission of the telnetd server program.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All users should upgrade to the latest available version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-crypt/heimdal-0.6.5"
