SynopsisThe remote Debian host is missing a security update.
DescriptionMultiple vulnerabilities have been found in qemu-kvm :
qemu-kvm built with the USB xHCI controller emulation support is vulnerable to an infinite loop issue. It could occur while processing USB command ring in 'xhci_ring_fetch'.
qemu-kvm built with the virtio-9p back-end support is vulnerable to a memory leakage issue. It could occur while doing a I/O read operation in v9fs_read() routine.
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.
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 'serial_update_parameters'.
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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected kvm, qemu-kvm, and qemu-kvm-dbg packages.
