Descriptions

The kadm5_modify_policy_internal function in lib/kadm5/srv/svr_policy.c in the Kerberos administration daemon (kadmind) in MIT Kerberos 5 (krb5) 1.5 through 1.6.2 does not properly check return values when the policy does not exist, which might allow remote authenticated users with the "modify policy" privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer.

La función kadm5_modify_policy_internal en lib/kadm5/srv/svr_policy.c del demonio de administración de Kerberos (kadmind) en MIT Kerberos 5 (krb5) 1.5 hasta 1.6.2 no comprueba adecuadamente los valores de retorno cuando no existe política, lo cual podría permitir a usuarios autenticados remotos con el privilegio de "modificar política" ejecutar código de su elección mediante vectores no especificados que provocan una escritura en un puntero no inicializado.
