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.
