SUN » Xvm Virtualbox : Security Vulnerabilities, CVEs,

Unspecified vulnerability in Guest Additions in Sun xVM VirtualBox 1.6.x and 2.0.x before 2.0.12, 2.1.x, and 2.2.x, and Sun VirtualBox before 3.0.10, allows guest OS users to cause a denial of service (memory consumption) on the guest OS via unknown vectors.

Sun xVM VirtualBox 2.0.0, 2.0.2, 2.0.4, 2.0.6r39760, 2.1.0, 2.1.2, and 2.1.4r42893 on Linux allows local users to gain privileges via a hardlink attack, which preserves setuid/setgid bits on Linux, related to DT_RPATH:$ORIGIN.

The VBoxDrvNtDeviceControl function in VBoxDrv.sys in Sun xVM VirtualBox before 1.6.4 uses the METHOD_NEITHER communication method for IOCTLs and does not properly validate a buffer associated with the Irp object, which allows local users to gain privileges by opening the \\.\VBoxDrv device and calling DeviceIoControl to send a crafted kernel address.
