Synopsis :

The remote VMware ESXi 5.5 host is potentially affected by multiple
vulnerabilities.

Description :

The remote VMware ESXi host is 5.5 prior to build 1746974 or 5.5
Update 1 prior to build 1746018. It is, therefore, potentially
affected by the following vulnerabilities in the OpenSSL library :

- 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
