3. Problem Description
a. VMware host memory overwrite vulnerability (data pointers)
Due to a flaw in the handler function for RPC commands, it is
possible to manipulate data pointers within the VMX process.
This vulnerability may allow a guest user to crash the VMX
process or potentially execute code on the host.
Workaround
- Configure virtual machines to use less than 4 GB of memory.
Virtual machines that have less than 4GB of memory are
not affected.
Mitigation
- Do not allow untrusted users access to your virtual machines.
Root or Administrator level permissions are not required to
exploit this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2012-1516 to this issue.
VMware would like to thank Derek Soeder of Ridgeway Internet
Security, L.L.C. for reporting this issue to us.
Column 4 of the following table lists the action required to
remediate the vulnerability in each release, if a solution is
available.

ESX 4.0 ESX ESX400-201105201-UG
ESX 3.5 ESX ESX350-201205401-SG
b. VMware host memory overwrite vulnerability (function pointers)
Due to a flaw in the handler function for RPC commands, it is
possible to manipulate function pointers within the VMX process.
This vulnerability may allow a guest user to crash the VMX
process or potentially execute code on the host.
Workaround
- None identified
Mitigation
- Do not allow untrusted users access to your virtual machines.
Root or Administrator level permissions are not required to
exploit this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org)

ESX 4.1 ESX ESX410-201201401-SG
ESX 4.0 ESX not affected
ESX 3.5 ESX not affected
c. ESX NFS traffic parsing vulnerability
Due to a flaw in the handling of NFS traffic, it is possible to
overwrite memory. This vulnerability may allow a user with access to
the network to execute code on the ESXi/ESX host without
authentication. The issue is not present in cases where there is no
NFS traffic.
Workaround
- None identified
Mitigation
- Connect only to trusted NFS servers
- Segregate the NFS network
- Harden your NFS server
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2012-2448 to this issue.

d. VMware floppy device out-of-bounds memory write
Due to a flaw in the virtual floppy configuration it is possible
to perform an out-of-bounds memory write. This vulnerability may allow
a
guest user to crash the VMX process or potentially execute code
on the host.
Workaround
- Remove the virtual floppy drive from the list of virtual IO
devices. The VMware hardening guides recommend removing unused
virtual IO devices in general.
Mitigation
- Do not allow untrusted root users in your virtual machines. Root or
Administrator level permissions are required to exploit this
issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2012-2449 to this issue.
Column 4 of the following table lists the action required to
remediate the vulnerability in each release, if a solution is
available.

** A workaround for the issue is listed above.
e. VMware SCSI device unchecked memory write
Due to a flaw in the SCSI device registration it is possible
to perform an unchecked write into memory. This vulnerability may
allow a guest user to crash the VMX process or potentially execute
code on the host.
Workaround
- Remove the virtual SCSI controller from the list of virtual IO
devices. The VMware hardening guides recommend removing unused
virtual IO devices in general.
Mitigation
- Do not allow untrusted root users access to your virtual machines.
Root or Administrator level permissions are required to exploit
this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
