CVE ID : CVE-2016-9911 CVE-2016-9921 CVE-2016-9922

Multiple vulnerabilities have been found in QEMU:

CVE-2016-9911

Quick Emulator (Qemu) 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

Quick emulator (Qemu) 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 packages.
