Description
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.SUSE information

Note from the SUSE Security Team
A vulnerability (named VENOM) in the floppy disk driver of qemu, Xen, and KVM allows attackers with root privileges to escape from a virtual machine (guest) and access the host system. The bug is not easy to exploit and might trigger crashes of the host system, that could be an indicator for an ongoing attack. All currently supported versions of SUSE Linux Enterprise Server starting from SUSE Linux Enterprise 10 SP3 up to and including SUSE Linux Enterprise 12 are affected by this vulnerability. SUSE (OpenStack) Cloud is affected too. Since the problematic code is in qemu, all versions of Xen, qemu and KVM are affected.
