Synopsis :

The remote service is affected by an information disclosure
vulnerability.

Description :

Based on its response to a TLS request with a specially crafted
heartbeat message (RFC 6520), the remote service appears to be
affected by an out-of-bounds read flaw.

This flaw could allow a remote attacker to read the contents of up to
64KB of server memory, potentially exposing passwords, private keys,
and other sensitive data.
