qemu: fdc: out-of-bounds fifo buffer memory access

An out-of-bounds memory access flaw was found in the way QEMU's virtual Floppy Disk Controller FDC handled FIFO buffer access while processing certain FDC commands. A privileged guest user could use this flaw to crash the guest or, potentially, execute arbitrary code on the host with the privileg...

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...
