Ooops... a typo in there.  Also, reformatted the rule string to
make it more readable.

better make that:

iptables -A INPUT -p tcp \! -f -m connbytes --conbytes 0:255 \
        -m state ESTABLISHED -m length --length 46:375 -m u32 \
        --u32 "o>>22&0x3C@ 12>>26&0x3C@  0=0x5353482D"     -j DROP
