Synopsis
========

A vulnerability in FreeRADIUS can lead to arbitrary code execution or
Denial of Service by authenticated users.

Background
==========

FreeRADIUS is an open source RADIUS authentication server.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-dialup/freeradius        < 2.2.5                    >= 2.2.5

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

Large passwords can trigger a stack-based buffer overflow in
FreeRADIUS's rlm_pap module when authenticating against an LDAP server.

Impact
======

An authenticated user could set a specially crafted long password,
possibly leading to arbitrary code execution or a Denial of Service
condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All FreeRADIUS users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-2.2.5"
