lsassd in Likewise Open /Enterprise 5.3 before build 7845, Open 6.0 before build 8325, and Enterprise 6.0 before build 178, as distributed in VMware ESXi 4.1 and ESX 4.1 and possibly other products, allows remote attackers to cause a denial of service (daemon crash) via an Active Directory login attempt that provides a username containing an invalid byte sequence.

Security readout for executives and security teams

CVE-2011-1786 is a remote denial-of-service issue in Likewise authentication services. A malformed Active Directory login username can crash lsassd, potentially disrupting authentication on affected systems, including VMware ESX/ESXi 4.1 distributions that included vulnerable Likewise components. Most likely exposure is legacy infrastructure running Likewise Open/Enterprise or VMware ESX/ESXi 4.1 with vulnerable Likewise components. Modern environments are exposed only if these old builds remain operational or embedded in another product. Treat this as a legacy availability risk. Prioritize if ESX/ESXi 4.1 or Likewise-backed authentication still supports business-critical systems; otherwise track as cleanup during legacy platform retirement. Mitigation focus: Upgrade Likewise 5.3 to build 7845 or later where applicable.; Upgrade Likewise Open 6.0 to build 8325 or later where applicable.; Upgrade Likewise Enterprise 6.0 to build 178 or later where applicable..
