Date:	09/22/2004
Bugs:	#60587
ID:	200409-29

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	Architecture(s)
net-dialup/freeradius	< 1.0.1	>= 1.0.1	All supported architectures

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
    
    # emerge -pv ">=net-dialup/freeradius-1.0.1"
    # emerge ">=net-dialup/freeradius-1.0.1"
