The VirtualBox family provides powerful x86 virtualization products.
Thomas Biege of SUSE discovered multiple vulnerabilities:
A local, unprivileged attacker with the permission to run VirtualBox could gain root privileges. A guest OS local user could cause a Denial of Service (memory consumption) on the guest OS via unknown vectors.
There is no known workaround at this time.
