Descriptions
Integer signedness error in the amd64_set_ldt function in sys/amd64/amd64/sys_machdep.c in FreeBSD 9.3 before p39, 10.1 before p31, and 10.2 before p14 allows local users to cause a denial of service (kernel panic) via an i386_set_ldt system call, which triggers a heap-based buffer overflow.
Error de entero sin signo en la función amd64_set_ldt en sys/amd64/amd64/sys_machdep.c en FreeBSD 9.3 en versiones anteriores a p39, 10.1 en versiones anteriores a p31 y 10.2 en versiones anteriores a p14 permite a usuarios locales provocar una denegación de servicio (pánico en el kernel) a través de una llamada i386_set_ldt system, lo que desencadena un desbordamiento de buffer basado en memoria dinámica.
