Detailsinfo

A vulnerability, which was classified as critical, was found in VMware Workstation and Fusion (Virtualization Software) (version now known). This affects some unknown processing of the component Drag/Drop. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability.

The bug was discovered 11/13/2016. The weakness was presented 11/14/2016 by Qinghao Tang (lokihardt) with 360 Marvel Team as New VMSA-2016-0019 - VMware product updates address multiple information disclosure issues as confirmed mailinglist post (Full-Disclosure). It is possible to read the advisory at seclists.org. This vulnerability is uniquely identified as CVE-2016-7461 since 09/09/2016. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The advisory points out:

The drag-and-drop (DnD) function in VMware Workstation and Fusion has an out-of-bounds memory access vulnerability. This may allow a guest to execute code on the operating system that runs Workstation or Fusion.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 95286 (VMware Fusion 8.x < 8.5.2 Drag-and-Drop Feature Arbitrary Code Execution (VMSA-2016-0019)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 370224 (VMware Workstation Pro, VMware Workstation Player and VMware Fusion out-of-bounds memory access vulnerability (VMSA-2016-0019)).

Upgrading eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (95286), SecurityFocus (BID 94280†) and SecurityTracker (ID 1037282†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
