Peter Jones d84e89f473 malloc: Use overflow checking primitives where we do complex allocations ... This attempts to fix the places where we do the following where arithmetic_expr may include unvalidated data: X = grub_malloc(arithmetic_expr); It accomplishes this by doing the arithmetic ahead of time using grub_add(), grub_sub(), grub_mul() and testing for overflow before proceeding. Among other issues, this fixes: - allocation of integer overflow in grub_video_bitmap_create() reported by Chris Coulson, - allocation of integer overflow in grub_png_decode_image_header() reported by Chris Coulson, - allocation of integer overflow in grub_squash_read_symlink() reported by Chris Coulson, - allocation of integer overflow in grub_ext2_read_symlink() reported by Chris Coulson, - allocation of integer overflow in read_section_as_string() reported by Chris Coulson.
