Descriptions

Stack-based buffer overflow in the normify function in the rlm_pap module (modules/rlm_pap/rlm_pap.c) in FreeRADIUS 2.x, possibly 2.2.3 and earlier, and 3.x, possibly 3.0.1 and earlier, might allow attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password hash, as demonstrated by an SSHA hash.

Desbordamiento de buffer basado en pila en la función normify en el módulo rlm_pap (modules/rlm_pap/rlm_pap.c) en FreeRADIUS 2.x, posiblemente 2.2.3 y anteriores, y 3.x, posiblemente 3.0.1 y anteriores, podría permitir a atacantes causar una denagción de servicio (caída) y posiblemente ejecutar código arbitrario a través de un hash de contraseña largo, tal y como fue demostrado por un hash SSHA.

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.

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.
