The owner module (xt_owner) matches the owner of the socket
# iptables -m owner --help
iptables v1.4.4
[...]
owner match options:
[!] --uid-owner userid[-userid] Match local UID
[!] --gid-owner groupid[-groupid] Match local GID
[!] --socket-exists Match if socket exists
man iptables for more details ;)
