Multiple vulnerabilities have been found in qemu-kvm:

CVE-2016-8576

to an infinite loop issue. It could occur while processing USB command ring
in &#x27;xhci_ring_fetch&#x27;.

CVE-2016-8577

leakage issue. It could occur while doing a I/O read operation in
v9fs_read() routine.

CVE-2016-8578

qemu-kvm built with the virtio-9p back-end support is vulnerable to a null
pointer dereference issue. It could occur while doing an I/O vector
unmarshalling operation in v9fs_iov_vunmarshal() routine.

CVE-2016-8669

qemu-kvm built with the 16550A UART emulation support is vulnerable to a
divide by zero issue. It could occur while updating serial device parameters
in &#x27;serial_update_parameters&#x27;.

For Debian 7 "Wheezy", these problems have been fixed in version
1.1.2+dfsg-6+deb7u17.

We recommend that you upgrade your qemu-kvm packages.
