Summary

VMware Tools for Windows update addresses an out of bounds read vulnerability in vm3dmp driver which is installed with vmtools in Windows guest machines. This issue is present in versions 10.2.x and 10.3.x prior to 10.3.10. A local attacker with non-administrative access to a Windows guest with VMware Tools installed may be able to leak kernel information or create a denial of service attack on the same Windows guest machine.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

descriptionThe version of VMware Tools installed on the remote Windows host is 10.2.x / 10.3.s prior to 10.3.10. It is, therefore, affected by an information disclosure / denial of service vulnerability due to an out of bounds read vulnerability in the vm3dmp driver which is installed with vmtools. An authenticated, local attacker could exploit this to leak kernel information or create a denial of service attack against the guest Windows machine vmtools is installed on. Note that Nessus has not tested for these issues but has instead relied only on the application
