Added 0002-commands-file-Fix-null-dereference.patch, #52771 |
The file command (and the grub-file utility) tries to dereference a null pointer when a file without valid ELF header is tested by one of the knetbsd tests:
The supplied patch fixes this and also serves as an example file to reproduce the error (even though any file without a valid ELF header should suffice).
