               VMware Security Advisory

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.

  1. 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.

  1. 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.

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.
