Synopsis
========

Multiple vulnerabilities have been found in MIT Kerberos 5, the most
severe of which may allow remote execution of arbitrary code.

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 < 1.9.2-r1 >= 1.9.2-r1

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

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

Impact
======

A remote attacker may be able to execute arbitrary code with the
privileges of the administration daemon or the Key Distribution Center
(KDC) daemon, cause a Denial of Service condition, or possibly obtain
sensitive information. Furthermore, a remote attacker may be able to
spoof Kerberos authorization, modify KDC responses, forge user data
messages, forge tokens, forge signatures, impersonate a client, modify
user-visible prompt text, or have other unspecified impact.

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-krb5-1.9.2-r1"
