"Multiple vulnerabilities were discovered in qemu, a fast processor
emulator. The Common Vulnerabilities and Exposures project identifies
the following problems :

CVE-2017-6505

Denial of service via infinite loop in the USB OHCI emulation

CVE-2017-8309

Denial of service via VNC audio capture

CVE-2017-10664

Denial of service in qemu-nbd server, qemu-io and qemu-img

CVE-2017-11434

Denial of service via a crafted DHCP options string

For Debian 7 'Wheezy', these problems have been fixed in version
1.1.2+dfsg-6+deb7u23.

We recommend that you upgrade your qemu packages.

"This update for xen fixes several issues. These security issues were
fixed :

  - Page transfer might have allowed PV guest to elevate
    privilege (XSA-217, bsc#1042882)

  - Races in the grant table unmap code allowed for
    informations leaks and potentially privilege escalation
    (XSA-218, bsc#1042893)

  - Insufficient reference counts during shadow emulation
    allowed a malicious pair of guest to elevate their
    privileges to the privileges that XEN runs under
    (XSA-219, bsc#1042915)

  - Missing NULL pointer check in event channel poll allows
    guests to DoS the host (XSA-221, bsc#1042924)

  - Stale P2M mappings due to insufficient error checking
    allowed malicious guest to leak information or elevate
    privileges (XSA-222, bsc#1042931)

  - Grant table operations mishandled reference counts
    allowing malicious guests to escape (XSA-224,
    bsc#1042938)

  - CVE-2017-9330: USB OHCI Emulation in qemu allowed local
    guest OS users to cause a denial of service (infinite
    loop) by leveraging an incorrect return value
    (bsc#1042160)

  - CVE-2017-8309: Memory leak in the audio/audio.c allowed
    remote attackers to cause a denial of service (memory
    consumption) by repeatedly starting and stopping audio
    capture (bsc#1037243)

  - PKRU and BND* leakage between vCPU-s might have leaked
    information to other guests (XSA-220, bsc#1042923)

The update package also includes non-security fixes. See advisory for
details.
