USN-7055-1: FreeRADIUS vulnerability | Ubuntu security notices

Packages

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.
