Summary

Several security issues were fixed in FreeRADIUS.

Details

It was discovered that FreeRADIUS incorrectly handled unix authentication.

A remote user could successfully authenticate with an expired password.

(CVE-2011-4966)

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)
