Perhaps something akin to the following for iptables filtering?

iptables -A OUTPUT -o eth0 -p tcp -m owner --cmd-owner acroread -j REJECT --reject-with tcp-reset

Since I don't have a PDF document with Javascript "web bug" in it, I tested the above with wget instead of acroread and it seems to work OK. Rejection with tcp-reset seems to avoid a several second delay that occurs with the default rejection method of ICMP port-unreachable.
