Comment # 6 on bug 9988 from 
Created attachment 13907 [details]
heartbeat requests with small payloads (and an invalid payload length)

Here is a testcase for small heartbeat requests. On current 1.12.7, it gives
"Malformed Packet".

Created with scapy:

    wrpcap("small-hb.pcap", [IP()/TCP(sport=42420+l, dport=443)/ \
    ("\x18\x03\x01\x00%s\01\xff\xff%s" % \
    (chr(3+l), l*"\xcc")) for l in (0, 1, 2, 3, 4, 15, 16, 17))
