Descriptions

The (1) execve and (2) fexecve system calls in the FreeBSD kernel 8.4 before p11, 9.1 before p14, 9.2 before p7, and 10.0 before p4 destroys the virtual memory address space and mappings for a process before all threads have terminated, which allows local users to cause a denial of service (triple-fault and system reboot) via a crafted system call, which triggers an invalid page table pointer dereference.

Las llamadas de sistema (1) execve y (2) fexecve en el kernel de FreeBSD 8.4 anterior a p11, 9.1 anterior a p14, 9.2 anterior a p7 y 10.0 anterior a p4 destruye los espacios y asignaciones del espacio de direcciones de memoria virtual para un proceso antes de que todos los hilos hayan terminado, lo que permite a usuarios locales causar una denegación de servicio (fallo triple y reinicio de sistema) a través de una llamada de sistema manipulada, lo que provoca una referencia a puntero de tabla de página inválida.

Several vulnerabilities have been discovered in the FreeBSD kernel that may lead to a denial of service or possibly disclosure of kernel memory.
