Privilege escalation via emulated floppy disk drive

ISSUE DESCRIPTION The code in qemu which emulates a floppy disk controller did not correctly bounds check accesses to an array and therefore was vulnerable to a buffer overflow attack. IMPACT A guest which has access to an emulated floppy device can exploit this vulnerability to take over the qem...
