Descriptions
In the Linux kernel, the following vulnerability has been resolved:
netlabel: fix out-of-bounds memory accesses
There are two array out-of-bounds memory accesses, one in
cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). Both
errors are embarassingly simple, and the fixes are straightforward.
As a FYI for anyone backporting this patch to kernels prior to v4.8,
you'll want to apply the netlbl_bitmap_walk() patch to
cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn't exist before
Linux v4.8.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netlabel: corrige accesos a memoria fuera de los límites Hay dos accesos a memoria fuera de los límites de matriz, uno en cipso_v4_map_lvl_valid() y el otro en netlbl_bitmap_walk(). Ambos errores son vergonzosamente simples y las soluciones son sencillas. Para su información, cualquiera que esté implementando este parche en kernels anteriores a v4.8, querrá aplicar el parche netlbl_bitmap_walk() a cipso_v4_bitmap_walk() ya que netlbl_bitmap_walk() no existe antes de Linux v4.8.
