Descriptions

The process_chpw_request function in schpw.c in the password-changing functionality in kadmind in MIT Kerberos 5 (aka krb5) 1.7 through 1.9 frees an invalid pointer, which allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a crafted request that triggers an error condition.

La función process_chpw_request de schpw.c en la funcionalidad de cambio de contraseña de kadmind de MIT Kerberos 5 (krb5) 1.7 hasta la 1.9 libera un puntero inválido, lo que permite a atacantes remotos ejecutar código de su elección o provocar una denegación de servicio (caída del demonio) a través de una petición modificada que provoca una condición de error.
