VMware Tools in VMware Workstation 10.x before 10.0.2, VMware Player 6.x before 6.0.2, VMware Fusion 6.x before 6.0.3, and VMware ESXi 5.0 through 5.5, when a Windows 8.1 guest OS is used, allows guest OS users to gain guest OS privileges or cause a denial of service (kernel NULL pointer dereference and guest OS crash) via unspecified vectors.

The remote VMware ESXi host is affected by a privilege escalation vulnerability due to a NULL pointer dereference flaw in VMware Tools running on Microsoft Windows 8.1. An attacker on an adjacent network can exploit this issue to gain elevated privileges within the guest operating system or else cause the guest operating system to crash.

The version of VMware Workstation installed on the remote host is version 10.x prior to 10.0.2. It is, therefore, reportedly affected by a privilege escalation vulnerability.

A kernel NULL dereference flaw exists in VMware tools on Windows 8.1 guest hosts. An attacker could escalate his privileges on the guest host.

Note that successful exploitation of the vulnerability does not allow privilege escalation from the guest host to the host system.

The installed version of VMware Player 6.x running on the remote Windows host is prior to 6.0.2. It is, therefore, reportedly affected by a privilege escalation vulnerability.

A kernel NULL dereference flaw exists in VMware tools on Windows 8.1 guest hosts. An attacker could escalate his privileges on the guest host.

Note that successful exploitation of the vulnerability does not allow privilege escalation from the guest host to the host system.

The installed version of VMware Player 6.x running on the remote Linux host is prior to 6.0.2. It is, therefore, reportedly affected by a privilege escalation vulnerability.

A kernel NULL dereference flaw exists in VMware tools on Windows 8.1 guest hosts. An attacker could escalate his privileges on the guest host.

Note that successful exploitation of the vulnerability does not allow privilege escalation from the guest host to the host system.

The version of VMware Fusion installed on the remote Mac OS X host is version 6.x prior to 6.0.3. It is, therefore, reportedly affected by a privilege escalation vulnerability.

A kernel NULL dereference flaw exists in VMware tools on Windows 8.1 guest hosts. An attacker could escalate his privileges on the guest host.

Note that successful exploitation of the vulnerability does not allow privilege escalation from the guest host to the host system.

a. Guest privilege escalation in VMware Tools

   A kernel NULL dereference vulnerability was found in VMware    Tools running on Microsoft Windows 8.1. Successful exploitation    of this issue could lead to an escalation of privilege in the    guest operating system.

   VMware would like to thank Tavis Ormandy from the Google Security    Team for reporting this issue to us.
    The vulnerability does not allow for privilege escalation from    the Guest Operating System to the host. This means that host    memory can not be manipulated from the Guest Operating System. 

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2014-3793 to this issue.
