OpenSSL 1.0.1 < 1.0.1g Multiple Vulnerabilities (Heartbleed)

High Nessus Plugin ID 73404

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.
