  - CVE-2017-9375: The USB xHCI controller emulator support     was vulnerable to an infinite recursive call loop issue,     which allowed a privileged user inside guest to crash     the Qemu process resulting in DoS (bsc#1042800).

  - CVE-2017-9374: Missing free of 's->ipacket', causes a     host memory leak, allowing for DoS (bsc#1043073).

  - CVE-2017-9373: The IDE AHCI Emulation support was     vulnerable to a host memory leakage issue, which allowed     a privileged user inside guest to leak host memory     resulting in DoS (bsc#1042801).

  - CVE-2017-8380: The MegaRAID SAS 8708EM2 Host Bus Adapter     emulation support was vulnerable to an out-of-bounds     read access issue which allowed a privileged user inside     guest to read host memory resulting in DoS     (bsc#1037336).

  - CVE-2016-9602: The VirtFS host directory sharing via     Plan 9 File System(9pfs) support was vulnerable to an     improper link following issue which allowed a privileged     user inside guest to access host file system beyond the     shared folder and potentially escalating their     privileges on a host (bsc#1020427).

  - CVE-2017-7471: The VirtFS host directory sharing via     Plan 9 File System(9pfs) support was vulnerable to an     improper access control issue which allowed a privileged     user inside guest to access host file system beyond the     shared folder and potentially escalating their     privileges on a host (bsc#1034866).

  - Fix privilege escalation in TCG mode of QEMU. This is     not considered a security issue by the upstream project,     but is included as additional hardening (bsc#1030624)

  - Fix potential DoS in virtfs

  - CVE-2016-10028: The Virtio GPU Device emulator support     was vulnerable to an out of bounds memory access issue     allowing a guest user to crash the Qemu process instance     on a host, resulting in DoS (bsc#1017084, bsc#1016503)

  - CVE-2016-10029: The Virtio GPU Device emulator support     was vulnerable to an OOB read issue allowing a guest     user to crash the Qemu process instance resulting in Dos     (bsc#1017081, bsc#1016504)

  - CVE-2017-5579: The 16550A UART serial device emulation     support was vulnerable to a memory leakage issue     allowing a privileged user to cause a DoS and/or     potentially crash the Qemu process on the host     (bsc#1021741)

  - CVE-2017-9503: The MegaRAID SAS 8708EM2 Host Bus Adapter     emulation support was vulnerable to a NULL pointer     dereference issue which allowed a privileged user inside     guest to crash the Qemu process on the host resulting in     DoS (bsc#1043296).
