Synopsis :

The remote VMware ESXi 5.5 host is affected by multiple

Description :

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.

- 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.

- 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.

- An unspecified privilege escalation vulnerability.

- An unspecified denial of service vulnerability due to an
input validation issue in the VMware Authorization
process (vmware-authd). (CVE-2015-1044)
