Synopsis ========
The EAP-MSCHAPv2 module of FreeRADIUS is affected by a validation issue which causes some authentication checks to be bypassed.
Background ==========
FreeRADIUS is an open source RADIUS authentication server implementation.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/freeradius < 1.1.1 >= 1.1.1 < 1.0.0
Description ===========
FreeRADIUS suffers from insufficient input validation in the EAP-MSCHAPv2 state machine.
Impact ======
An attacker could cause the server to bypass authentication checks by manipulating the EAP-MSCHAPv2 client state machine.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All FreeRADIUS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.1.1"
