The vulnerability of VMnetDHCP hypervisors in VMware Workstation and VMware Fusion allows a perpetrator to gain unauthorized access to protected information.

The vulnerability of VMnetDHCP hypervisors in VMware Workstation and VMware Fusion lies in the lack of protection for service-related data. Exploiting this vulnerability can allow an attacker, operating remotely, to gain unauthorized access to protected information...

Microsoft Windows Uninitialized Variable Local Privilege Elevation

This module exploits CVE-2019-1458, an arbitrary pointer dereference vulnerability within win32k which occurs due to an uninitalized variable, which allows user mode attackers to write a limited amount of controlled data to an attacker controlled address in kernel memory. By utilizing this...

Failure Modes in Machine Learning

Interesting taxonomy of machine-learning failures pdf that encompasses both mistakes and attacks, or -- in their words -- intentional and unintentional failure modes. It's a good basis for threat modeling...

Unspecified vulnerability in ShapeShift KeepKey finite state machine

ShapeShift KeepKey is an e-wallet device for cryptocurrency storage. An unspecified vulnerability exists in the ShapeShift KeepKey finite state machine, which stems from the program not being sufficiently authenticated.
