Synopsis :

The remote VMware ESXi 5.1 host is affected by a guest privilege
escalation vulnerability.

Description :

The remote VMware ESXi 5.1 host is prior to build 3070626. It is,
therefore, affected by a guest privilege escalation vulnerability in
the Shared Folders (HGFS) feature due to improper validation of
user-supplied input. A local attacker can exploit this to corrupt
memory, resulting in an elevation of privileges.
