      "value": "A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the application, possibly resulting in a denial of service (DoS) attack."

Las rutinas de descifrado DES y Triple-DES de la biblioteca GSSAPI de Heimdal permiten un desbordamiento del b\u00fafer de escritura de longitud limitada en la memoria asignada a malloc() cuando se presenta un paquete maliciosamente peque\u00f1o. Este fallo permite a un usuario remoto enviar datos maliciosos especialmente manipulados a la aplicaci\u00f3n, lo que puede provocar un ataque de denegaci\u00f3n de servicio (DoS)."
