New! Plugin Severity Now Using CVSS v3

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.
Solution
Upgrade to OpenSSL 1.0.1g or later.Alternatively, recompile OpenSSL with the '-DOPENSSL_NO_HEARTBEATS' flag to disable the vulnerable functionality.
