CVE-2019-25160

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2019-25160
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.

Summary
  • (es) 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.
