Redhat » Enterprise Virtualization : Security Vulnerabilities, CVEs, Published In 2015

The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.

The Web Admin interface in Red Hat Enterprise Virtualization Manager (RHEV-M) allows local users to bypass the timeout function by selecting a VM in the VM grid view.
