Descriptions
A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability.
Se ha encontrado un fallo en samba. Los espacios usados en una cadena alrededor de un nombre de dominio (DN), aunque se supone que deben ser ignorados, pueden causar cadenas DN no válidas con espacios en lugar de escribir un byte cero en la memoria fuera de límites, resultando en un bloqueo. La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema
