| Beschreibung: | Summary:
The remote ESXi is missing one or more security related Updates from VMSA-2011-0007.
Vulnerability Insight:
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.
