(bsc#864769).
- CVE-2013-4539: Multiple buffer overflows in the tsc210x_load function in

- CVE-2014-9718: The (1) BMDMA and (2) AHCI HBA interfaces in the IDE
functionality had multiple interpretations of a function's return value,
which allowed guest OS users to cause a host OS denial of service
(memory consumption or infinite loop, and system crash) via a PRDT with
zero complete sectors, related to the bmdma_prepare_buf and
ahci_dma_prepare_buf functions (bsc#928393).
- CVE-2015-1779: The VNC websocket frame decoder allowed remote attackers
to cause a denial of service (memory and CPU consumption) via a large
(1) websocket payload or (2) HTTP headers section (bsc#924018).
- CVE-2015-5278: Infinite loop in ne2000_receive() function (bsc#945989).
