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"
