Synopsis
========

Certain Heimdal components, ftpd and rcp, are vulnerable to a local
privilege escalation.

Background
==========

Heimdal is a free implementation of Kerberos 5.

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  app-crypt/heimdal     < 0.7.2-r3                      >= 0.7.2-r3

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

The ftpd and rcp applications provided by Heimdal fail to check the
return value of calls to seteuid().

Impact
======

A local attacker could exploit this vulnerability to execute arbitrary
code with elevated privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Heimdal users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-crypt/heimdal-0.7.2-r3"
