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-2010-1323 CVE-2010-4020 CVE-2010-4021
                   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.

    VMware         Product   Running  Replace with/
    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.

    remediate the vulnerability in each release, if a solution is
    available.

    The Service Console kernel is updated to include a fix for a
    security issue.
    
    The Common Vulnerabilities and Exposures project (cve.mitre.org) has
