Red Hat Security Advisory 2015-1287-01 - FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service server, designed to allow centralized authentication and authorization for a network. A stack-based buffer overflow was found in the way the FreeRADIUS rlm_pap module handled long password hashes. An attacker able to make radiusd process a malformed password hash could cause the daemon to crash. The freeradius packages have been upgraded to upstream version 2.2.6, which provides a number of bug fixes and enhancements over the previous version.

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. Various other issues were also addressed.
