Synopsis
========

Multiple vulnerabilities have been discovered in MIT Kerberos 5,
allowing execution of arbitrary code or Denial of Service.

Background
==========

MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-crypt/mit-krb5           < 1.11.4                  >= 1.11.4

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

Multiple vulnerabilities have been discovered in the Key Distribution
Center in MIT Kerberos 5. Please review the CVE identifiers referenced
below for details.

Impact
======

A remote attacker could send a specially crafted request, possibly
resulting in execution of arbitrary code with the privileges of the
process or a Denial of Service condition. Additionally, a remote
attacker could impersonate a kadmind server and send a specially
crafted packet to the password change port, which can result in a
ping-pong condition and a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MIT Kerberos 5 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.11.4"
