Detailsinfo

A vulnerability classified as problematic has been found in VMware Player, Workstation, Fusion and ESXi on Windows 8.1 (Virtualization Software). This affects an unknown part of the component Tools. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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 weakness was released 05/29/2014 by Tavis Ormandy with Google Security Team as VMSA-2014-0005 as confirmed advisory (Website). The advisory is shared at vmware.com. The public release was coordinated with VMware. This vulnerability is uniquely identified as CVE-2014-3793 since 05/20/2014. The exploitability is told to be difficult. An attack has to be approached locally. A authentication is necessary for exploitation. Neither technical details nor an exploit are publicly available. The advisory points out:

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 vulnerability scanner Nessus provides a plugin with the ID 74265 (VMware Player 6.x < 6.0.2 Windows 8.1 Guest Privilege Escalation (VMSA-2014-0005)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows. The commercial vulnerability scanner Qualys is able to test this issue with plugin 216070 (VMware ESXi 5.0.0 Patch Release ESXi500-201405001 Missing (KB2075521)).

Applying a patch is able to eliminate this problem. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (93498), Tenable (74265), SecurityFocus (BID 67737†), Secunia (SA58894†) and SecurityTracker (ID 1030311†).
