  • Fix DOS in virtio-9pfs (CVE-2016-8578 bsc#1003894)
  • Fix DOS in virtio-9pfs (CVE-2016-9105 bsc#1007494)
  • Fix DOS in virtio-9pfs (CVE-2016-8577 bsc#1003893)
  • Plug data leak in virtio-9pfs interface (CVE-2016-9103 bsc#1007454)
  • Fix DOS in virtio-9pfs interface (CVE-2016-9102 bsc#1007450)
  • Fix DOS in virtio-9pfs (CVE-2016-9106 bsc#1007495)
  • Fix DOS in 16550A UART emulation (CVE-2016-8669 bsc#1004707)
  • Fix DOS in PC-Net II emulation (CVE-2016-7909 bsc#1002557)
  • Fix DOS in PRO100 emulation (CVE-2016-9101 bsc#1007391)
  • Fix DOS in RTL8139 emulation (CVE-2016-8910 bsc#1006538)
  • Fix DOS in Intel HDA controller emulation (CVE-2016-8909 bsc#1006536)
  • Fix DOS in virtio-9pfs (CVE-2016-9104 bsc#1007493)
  • Fix DOS in JAZZ RC4030 emulation (CVE-2016-8667 bsc#1004702)
  • Patch queue updated from https://gitlab.suse.de/virtualization/qemu.git SLE11-SP4
  • Remove semi-contradictory and now determined erroneous statement in kvm-supported.txt regarding not running ntp in kvm guest when kvm-clock is used. It is now recommended to use ntp in guest in this case.
