  script_tag(name:"insight", value:"VMware ESXi and ESX could encounter a socket exhaustion situation which may lead to
  a denial of service. Updates to Likewise components and to the ESX Service Console address security vulnerabilities.

  a. ESX/ESXi Socket Exhaustion

  By sending malicious network traffic to an ESXi or ESX host an attacker could
  exhaust the available sockets which would prevent further connections to the
  host. In the event a host becomes inaccessible its virtual machines will
  continue to run and have network connectivity but a reboot of the ESXi or ESX
  host may be required in order to be able to connect to the host again.

  ESXi and ESX hosts may intermittently lose connectivity caused by applications
  that do not correctly close sockets. If this occurs an error message similar to
  the following may be written to the vpxa log:

  socket() returns -1 (Cannot allocate memory)

  An error message similar to the following may be written to the vmkernel logs:

  socreate(type=2, proto=17) failed with error 55

  b. Likewise package update

  Updates to the vmware-esx-likewise-openldap and vmware-esx-likewise-krb5
  packages address several security issues.

  One of the vulnerabilities is specific to Likewise while the other
  vulnerabilities are present in the MIT version of krb5. An incorrect assert()
  call in Likewise may lead to a termination of the Likewise-open lsassd service
  if a username with an illegal byte sequence is entered for user authentication
  when logging in to the Active Directory domain of the ESXi/ESX host. This would
  lead to a denial of service. The MIT-krb5 vulnerabilities are detailed in
  MITKRB5-SA-2010-007.

  c. ESX third party update for Service Console kernel

  The Service Console kernel is updated to include a fix for a security issue.");
