The VBoxSF.sys driver is a component of VirtualBox Guest Additions, which is in charge of providing the 'Shared Folders' feature offered by Oracle VirtualBox.

This driver doesn't properly validate a pointer when handling the IOCTL_MRX_VBOX_DELCONN IoControl. This allows an unprivileged user in a Windows Guest OS with VirtualBox Guest Additions installed to gain SYSTEM privileges within the Guest OS.
The code that implements 3D acceleration for OpenGL graphics in Oracle VirtualBox is prone to multiple memory corruption vulnerabilities.

An attacker running code within a Guest operating system can exploit these vulnerabilities in order to escape from the virtual machine and execute arbitrary code on the Host operating system.
