Core dump file from ipset
Trying to pass arguments via xargs to ipset I ran across a buffer overflow in
the argument parsing ipset_parse_argv function. I've reproduced this error on
Manjaro and Ubuntu Linux systems. The error can be triggered by trying to add
more than 32 arguments (more than MAX_ARGS define) to the ipset command.
Example: ipset add a $(perl -e 'print "A "x64;')
