OpenSSL Heartbeat Information Disclosure (Heartbleed)

high Nessus Network Monitor Plugin ID 7108
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote service is affected by an information disclosure vulnerability.

Description

The remote host is configured with the TLS heartbeat message feature and 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.
