Advisory ID:       VMSA-2011-0007
Synopsis:          VMware ESXi and ESX Denial of Service and third party
                  updates for Likewise components and ESX Service
                  Console
Issue date:        2011-04-28
Updated on:        2011-04-28
CVE numbers:       CVE-2011-1785 CVE-2011-1786 CVE-2010-1324

                  CVE-2010-2240
- ------------------------------------------------------------------------

1. Summary

  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.

2. Relevant releases

  VMware ESXi 4.1 without patch ESXi410-201104401-SG.
  VMware ESXi 4.0 without patch ESXi400-201104401-SG.

  VMware ESX 4.1 without patch ESX410-201104401-SG.
  VMware ESX 4.0 without patch ESX400-201104401-SG.

3. Problem Description

 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

   VMware would like to thank Jimmy Scott at inet-solutions.be for
   reporting this issue to us.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org) has
   assigned the name CVE-2011-1785 to this issue.

   Column 4 of the following table lists the action required to
   remediate the vulnerability in each release, if a solution is
   available.

   Product        Version   on       Apply Patch

 * hosted products are VMware Workstation, Player, ACE, Fusion.

 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.

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has
   assigned the names CVE-2011-1786 (Likewise-only issue),
   CVE-2010-1324, CVE-2010-1323, CVE-2010-4020, CVE-2010-4021 to these
   issues.

   Column 4 of the following table lists the action required to
   remediate the vulnerability in each release, if a solution is
   available.

 c. ESX third party update for Service Console kernel

   security issue.
