Descriptions

Integer overflow in the vma_to_resize function in mm/mremap.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service (BUG_ON and system crash) via a crafted mremap system call that expands a memory mapping.

Desbordamiento de entero en la función vma_to_resize de mm/mremap.c del kernel de Linux en versiones anteriores a la 2.6.39. Permite a usuarios locales provocar una denegación de servicio (BUG_ON y caída del sistema) a través de una llamada del sistema mremap modificada que expande el mapeo de memoria ("memory mapping").
