Package        : qemu-kvm
CVE ID         : CVE-2015-5165 CVE-2015-5745

Several vulnerabilities were discovered in qemu-kvm, a full
virtualization solution on x86 hardware.

CVE-2015-5165

    Donghai Zhu discovered that the QEMU model of the RTL8139 network
    card did not sufficiently validate inputs in the C+ mode offload
    emulation, allowing a malicious guest to read uninitialized memory
    from the QEMU process's heap.

CVE-2015-5745

    A buffer overflow vulnerability was discovered in the way QEMU
    handles the virtio-serial device. A malicious guest could use this
    flaw to mount a denial of service (QEMU process crash).

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.1.2+dfsg-6+deb7u9.

We recommend that you upgrade your qemu-kvm packages.
