Descriptions

There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer.

Se presenta un problema de uso de la memoria previamente liberada en todas las versiones 4.9.x anteriores a 4.9.18 de samba, todas las versiones 4.10.x anteriores a 4.10.12 de samba y todas las versiones 4.11.x anteriores a 4.11.5 de samba, esencialmente debido a una llamada a la función realloc() mientras que otras variables locales aún apuntan al búfer original.
