medium Nessus Plugin ID 87676
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 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 ensure 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.
