VMware vCenter is the centralized management tool for the vSphere suite. The target is missing Update 3b, which corrects the following security issue:
A local user on the host system can exploit an insecure library loading flaw in the LD_LIBRARY_PATH variable and cause the target user to load an arbitrary shared library to obtain elevated privileges on the host system [CVE-2017-4921].
The service startup script uses directories with world writable permissions for storing critical information in temporary files [CVE-2017-4922]. A local user on the host system can access critical information when the service is restarted.
A local user can exploit a flaw in the vCenter Server Appliance file-based backup feature to obtain plaintext credentials [CVE-2017-4923].
