Ubuntu Security Notice USN-7055-1
October 03, 2024

freeradius vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

A system authentication measure could be bypassed.

Software Description:
- freeradius: high-performance and highly configurable RADIUS server

Details:

Goldberg, Miro Haller, Nadia Heninger, Mike Milano, Dan Shumow, Marc
Stevens, and Adam Suhl discovered that FreeRADIUS incorrectly authenticated
certain responses. An attacker able to intercept communications between a
RADIUS client and server could possibly use this issue to forge responses,
bypass authentication, and access network devices and services.

This update introduces new configuration options called "limit_proxy_state"
and "require_message_authenticator" that default to "auto" but should be
set to "yes" once all RADIUS devices have been upgraded on a network.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
freeradius 3.2.5+dfsg-3~ubuntu24.04.1

Ubuntu 22.04 LTS
freeradius 3.0.26~dfsg~git20220223.1.00ed0241fa-0ubuntu3.3

Ubuntu 20.04 LTS
freeradius 3.0.20+dfsg-3ubuntu0.4

In general, a standard system update will make all the necessary changes.
