========================================================================== 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.
