It was discovered that FreeRADIUS incorrectly handled unix authentication.
A remote user could successfully authenticate with an expired password.
Pierre Carrier discovered that FreeRADIUS incorrectly handled rlm_pap
hash processing. An authenticated user could use this issue to cause
FreeRADIUS to crash, resulting in a denial of service, or possibly execute
arbitrary code. The default compiler options for affected releases should
reduce the vulnerability to a denial of service. (CVE-2014-2015)
