Description:	Summary: The remote host is missing an update for the Debian 'qemu-kvm' package(s) announced via the DLA-765-1 advisory. Vulnerability Insight: Multiple vulnerabilities have been found in qemu-kvm: CVE-2016-9911 qemu-kvm built with the USB EHCI Emulation support is vulnerable to a memory leakage issue. It could occur while processing packet data in ehci_init_transfer. A guest user/process could use this issue to leak host memory, resulting in DoS for a host. CVE-2016-9921 / CVE-2016-9922 qemu-kvm built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS. For Debian 7 Wheezy, these problems have been fixed in version 1.1.2+dfsg-6+deb7u19. We recommend that you upgrade your qemu-kvm packages.
