The remote Debian host is missing a security-related update.


Several vulnerabilities were discovered in the qemu virtualisation solution :

- CVE-2014-9718 It was discovered that the IDE controller emulation is susceptible to denial of service.

- CVE-2015-1779 Daniel P. Berrange discovered a denial of service vulnerability in the VNC web socket decoder.

- CVE-2015-3456 Jason Geffner discovered a buffer overflow in the emulated floppy disk drive, resulting in the potential execution of arbitrary code.


Upgrade the qemu packages.

For the oldstable distribution (wheezy), these problems have been fixed in version 1.1.2+dfsg-6+deb7u7 of the qemu source package and in version 1.1.2+dfsg-6+deb7u7 of the qemu-kvm source package. Only CVE-2015-3456 affects oldstable.

For the stable distribution (jessie), these problems have been fixed in version 1:2.1+dfsg-12.
