The remote VMware ESXi host is version 5.5 prior to build 2352327. It is, therefore, affected by the following vulnerabilities :
An error exists related to DTLS SRTP extension handling and specially crafted handshake messages that can allow denial of service attacks via memory leaks.
(CVE-2014-3513)
An error exists related to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. A man-in-the-middle attacker can decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. This is also known as the ‘POODLE’ issue. (CVE-2014-3566)
An error exists related to session ticket handling that can allow denial of service attacks via memory leaks.
(CVE-2014-3567)
An error exists related to the build configuration process and the ‘no-ssl3’ build option that allows servers and clients to process insecure SSL 3.0 handshake messages. (CVE-2014-3568)
A denial of service vulnerability in libxml2 due to entity expansion even when entity substitution is disabled. A remote attacker, using a crafted XML document containing larger number of nested entity references, can cause the consumption of CPU resources.
(CVE-2014-3660)
An unspecified privilege escalation vulnerability.
(CVE-2014-8370)
An unspecified denial of service vulnerability due to an input validation issue in the VMware Authorization process (vmware-authd). (CVE-2015-1044)
