Title: FreeRADIUS: Security bypass (GLSA 201706-27)
A vulnerability in FreeRADIUS might allow remote attackers to
FreeRADIUS is an open source RADIUS authentication server.
Vulnerable: < 3.0.14
Unaffected: >= 3.0.14
Architectures: All supported architectures
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
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"
