VMware ESXi/Workstation/Fusion Shader Translator out-of-bounds

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as critical, was found in VMware ESXi, Workstation and Fusion (Virtualization Software) (version now known). This affects some unknown processing of the component Shader Translator. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

VMware ESXi (6.7 before ESXi670-201904101-SG and 6.5 before ESXi650-201903001), Workstation (15.x before 15.0.3 and 14.x before 14.1.6), Fusion (11.x before 11.0.3 and 10.x before 10.1.6) contain multiple out-of-bounds read vulnerabilities in the shader translator. Exploitation of these issues requires an attacker to have access to a virtual machine with 3D graphics enabled. Successful exploitation of these issues may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on their own VM. The workaround for these issues involves disabling the 3D-acceleration feature. This feature is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.

The bug was discovered 04/11/2019. The weakness was shared 04/15/2019 by Richard Zhu with Fluoroacetate (Website). It is possible to read the advisory at vmware.com. This vulnerability is uniquely identified as CVE-2019-5517 since 01/07/2019. 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 vulnerability was handled as a non-public zero-day exploit for at least 4 days. During that time the estimated underground price was around $5k-$25k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 371743 (VMware Workstation (14.x,15.x), Fusion (10.x,11.x) Multiple Out-of-Bounds Read Vulnerabilities (VMSA-2019-0006)).

Upgrading eliminates this vulnerability.
