Multiple security issues have been found in the Xen virtualisation solution, which may result in denial of service or information disclosure.

The oldstable distribution (wheezy) will be updated in a separate DSA.

This update fixes the following security issues :

  - bsc#955399 - Fix xm migrate --log_progress. Due to logic     error progress was not logged when requested.

  - bsc#956832 - CVE-2015-8345: xen: qemu: net: eepro100:
    infinite loop in processing command block list

  - bsc#956592 - xen: virtual PMU is unsupported (XSA-163)

  - bsc#956408 - CVE-2015-8339, CVE-2015-8340: xen:
    XENMEM_exchange error handling issues (XSA-159)

  - bsc#956409 - CVE-2015-8341: xen: libxl leak of pv kernel     and initrd on error (XSA-160)

  - bsc#956411 - CVE-2015-7504: xen: heap buffer overflow     vulnerability in pcnet emulator (XSA-162)

  - bsc#947165 - CVE-2015-7311: xen: libxl fails to honour     readonly flag on disks with qemu-xen (xsa-142)

  - bsc#955399 - Fix xm migrate --live. The options were not     passed due to a merge error. As a result the migration     was not live, instead the suspended guest was migrated.

  - bsc#954405 - CVE-2015-8104: Xen: guest to host DoS by     triggering an infinite loop in microcode via #DB     exception

  - bsc#954018 - CVE-2015-5307: xen: x86: CPU lockup during     fault delivery (XSA-156)

  - bsc#950704 - CVE-2015-7970: xen: x86: Long latency     populate-on-demand operation is not preemptible     (XSA-150)

  - bsc#951845 - CVE-2015-7972: xen: x86: populate-on-demand     balloon size inaccuracy can crash guests (XSA-153)

  - Drop     5604f239-x86-PV-properly-populate-descriptor-tables.patc     h

  - bsc#950703 - CVE-2015-7969: xen: leak of main per-domain     vcpu pointer array (DoS) (XSA-149)

  - bsc#950705 - CVE-2015-7969: xen: x86: leak of per-domain     profiling-related vcpu pointer array (DoS) (XSA-151)
