Descriptions

The (1) ssh2_load_userkey and (2) ssh2_save_userkey functions in PuTTY 0.51 through 0.63 do not properly wipe SSH-2 private keys from memory, which allows local users to obtain sensitive information by reading the memory.

Las funciones (1) ssh2_load_userkey y (2) ssh2_save_userkey en PuTTY 0.51 hasta 0.63 no limpian correctamente las claves privadas SSH-2 de la memoria, lo que permite a usuarios remotos obtener información sensible mediante la lectura de la memoria.
