Synopsis
========
Multiple Denial of Service vulnerabilities were found and fixed in
FreeRADIUS.
Background
==========
FreeRADIUS is an open source RADIUS authentication server
implementation.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

1 net-dialup/freeradius < 1.0.1 >= 1.0.1
Description
===========
There are undisclosed defects in the way FreeRADIUS handles incorrect
received packets.
Impact
======
A remote attacker could send specially-crafted packets to the
FreeRADIUS server to deny service to other users by crashing the
server.
Workaround
==========
There is no known workaround at this time.
Resolution

All FreeRADIUS users should upgrade to the latest version:
# emerge sync
