A vulnerability in FreeRADIUS might allow remote attackers to bypass authentication.
|Package||net-dialup/freeradius on all architectures|
|Affected versions||< 3.0.14|
|Unaffected versions||>= 3.0.14|
FreeRADIUS is an open source RADIUS authentication server.
It was discovered that the implementation of TTLS and PEAP in FreeRADIUS skips inner authentication when it handles a resumed TLS connection. The affected versions of FreeRADIUS fails to reliably prevent the resumption of unauthenticated sessions unless the TLS session cache is disabled completely.
An unauthenticated remote user can bypass authentication by starting a session, and then resuming an unauthenticated TLS session before inner authentication has been completed successfully.
Set “enabled = no” in the cache subsection of eap module settings to disable TLS session caching.
All FreeRADIUS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-3.0.14"
