OpenBSD uses the fileutils-4.0 for the "gnuls" port. I
was browsing rootshell a while back and i found an
advisory for older systems which used the -w switch
without limit checking. ls -w 50000000 would eat ram,
eat swap, and eventually crash the system. I know very
little C, so i could not fix -w to check a limit, but
i was able to remove the -w switch from ls.c and
mention of it in the man page. The uuencoded patch is
given below:
