Oracle, which develops VirtualBox, said in an emailed statement that the company was "aware" of the problem, and fixed the code, adding that it will release a maintenance update soon.
"We will release a VirtualBox 4.3 maintenance release very soon. Apart from this, only a limited amount of users should be affected as the floppy device emulation is disabled for most of the standard virtual machine configurations," said software lead Frank Mehnert.
