Synopsis ========
A vulnerability in FreeRADIUS might allow remote attackers to bypass authentication.
Background ==========
FreeRADIUS is an open source RADIUS authentication server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/freeradius < 3.0.14 >= 3.0.14
Description ===========
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.
Impact ======
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.
Workaround ==========
Set "enabled = no" in the cache subsection of eap module settings to disable TLS session caching.
Resolution ==========
All FreeRADIUS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-3.0.14"
References ==========
