Multiple serious vulnerabilities have been found in VMware Workstation Pro and VMware Workstation Player. Malicious users can exploit these vulnerabilities to gain privileges or cause a denial of service.

Below is a complete list of vulnerabilities:

1. A DLL loading vulnerability can be exploited remotely to gain privileges from normal to System in the host machine;
2. An unspecified vulnerability in the SVGA driver can be exploited remotely to cause a denial of service on the virtual machine or out-of-bounds read.
3. A NULL pointer dereference vulnerability in the SVGA driver can be exploited remotely by malicious users with normal privileges to cause a denial of service on their virtual machines.

Technical details

Vulnerability (1) is related to the “vmware-vmx” process, which loads DLLs from a path defined in the local environment variable.

Vulnerability (2) can be exploited only in case the host does not have any graphics card or graphics drivers installed.
