The remote VMware ESXi 5.0 host is affected by the following security vulnerabilities :
An error exists related to NFS traffic handling that could allow memory corruption leading to execution of arbitrary code. (CVE-2012-2448)
Out-of-bounds write errors exist related to virtual floppy disc devices and virtual SCSI devices that could allow local privilege escalation. (CVE-2012-2449, CVE-2012-2450)
