VMware ESXi Multiple OpenSSL Vulnerabilities (VMSA-2014-0004) (Heartbleed)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote VMware ESXi host is missing a security-related patch.

Description :

The remote VMware ESXi host is affected by multiple vulnerabilities
in the OpenSSL third-party library :

- A flaw exist in the Elliptic Curve Digital Signature
Algorithm (ECDSA) implementation due to a failure to
insure that certain swap operations have a constant-time
behavior. An attacker can exploit this to obtain the
ECDSA nonces by using a FLUSH+RELOAD cache side-channel
attack. (CVE-2014-0076)

- An out-of-bounds read error, known as Heartbleed, exists
in the TLS/DTLS implementation due to improper handling
of TLS heartbeat extension packets. A remote attacker,
using crafted packets, can trigger a buffer over-read,
resulting in the disclosure of up to 64KB of process
memory, which contains sensitive information such as
primary key material, secondary key material, and other
protected content. (CVE-2014-0160)

Solution :

Apply the appropriate patch according to the vendor advisory that
pertains to ESXi version 5.5 / 5.5 U1. Additional remediation steps
may also need to be performed after applying the patch.

Risk factor :

High / CVSS Base Score : 9.4

CVSS Temporal Score : 7.4
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
