OpenSSL 1.0.1 < 1.0.1g Multiple Vulnerabilities (Heartbleed)

medium Nessus Plugin ID 73404
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 may be affected by multiple vulnerabilities.

Description

According to its banner, the remote web server uses a version of OpenSSL 1.0.1 prior to 1.0.1g. The OpenSSL library is, therefore, reportedly affected by the following vulnerabilities :

- An error exists related to the implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) that could allow nonce disclosure via the 'FLUSH+RELOAD' cache side-channel attack. (CVE-2014-0076)

- An out-of-bounds read error, known as the 'Heartbleed Bug', exists related to handling TLS heartbeat extensions that could allow an attacker to obtain sensitive information such as primary key material, secondary key material and other protected content.
(CVE-2014-0160)

Solution

Upgrade to OpenSSL 1.0.1g or later.

Alternatively, recompile OpenSSL with the '-DOPENSSL_NO_HEARTBEATS' flag to disable the vulnerable functionality.
