NetBSD contains a flaw that may allow a local denial of service. The issue is triggered when the elf_load_file() function dereferences a NULL pointer. The NULL pointer dereference occurs when a malicious user creates an elf interpreter that lacks a PT_LOAD section in its header. This will result in loss of availability for the platform.
