crafted (1) cmd_len, (2) row, or (3) col values; (4) row_start and
row_end values; or (5) col_star and col_end values in a savevm image
(bsc#864769).
- CVE-2013-4539: Multiple buffer overflows in the tsc210x_load function in

(XSA-165) (bsc#958009).
- CVE-2015-8558: Infinite loop in ehci_advance_state resulted in DoS
(bsc#959005).

- CVE-2015-8745: Reading IMR registers lead to a crash via assert(2) call
(bsc#960707).
- CVE-2016-1570: The PV superpage functionality in arch/x86/mm.c allowed
local PV guests to obtain sensitive information, cause a denial of
service, gain privileges, or have unspecified other impact via a crafted
page identifier (MFN) to the (1) MMUEXT_MARK_SUPER or (2)
MMUEXT_UNMARK_SUPER sub-op in the HYPERVISOR_mmuext_op hypercall or (3)
unknown vectors related to page table updates (bsc#960861).
