Name of the Vulnerable Software and Affected Versions: Oracle VM VirtualBox versions prior to 6.1.20

Description: The issue is related to insufficient input validation in the Core component of Oracle VM VirtualBox, which can be exploited to cause a denial of service. This vulnerability allows a high-privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox, resulting in the ability to cause a hang or frequently repeatable crash of Oracle VM VirtualBox. The vulnerability specifically affects Windows systems.
