Why heart bleed?
TLS HearBeat Extension.
The vulnerability lies in the implementation of TLS
Heartbeat extension. There is common necessity
in an established ssl session to maintain the
connection for a longer time. The HeartBeat
protocol extension is added to TLS for this reason.
The HTTP keep-alive feature does the same but HB
protocol allows a client to perform this action in
much higher rate.
The client can send a Heart-Beat request message
and the server has to respond back with a
HearBeat response .
• We can leak 64 kb of memory and that
could easily have usernames/password,
private keys etc.
• Constant HB request could be made to
the server leaking (random memory)
any amount of data from the server .
