Name of the Vulnerable Software and Affected Versions Oracle VM VirtualBox versions prior to 6.1.28

Description The issue is related to a buffer overflow in the Core component of Oracle VM VirtualBox, which can be exploited to cause a denial of service. A high-privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes can compromise Oracle VM VirtualBox, resulting in the ability to cause a hang or frequently repeatable crash.

Recommendations For versions prior to 6.1.28, update to version 6.1.28 or later to resolve the issue. As a temporary workaround, consider restricting access to the Core component of Oracle VM VirtualBox to minimize the risk of exploitation.
