Package        : qemu-kvm
CVE ID         : CVE-2015-3209 CVE-2015-4037
Debian Bug     : 788460

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

CVE-2015-3209

    Matt Tait of Google's Project Zero security team discovered a flaw
    in the way QEMU's AMD PCnet Ethernet emulation handles multi-TMD
    packets with a length above 4096 bytes. A privileged guest user in a
    guest with an AMD PCNet ethernet card enabled can potentially use
    this flaw to execute arbitrary code on the host with the privileges
    of the hosting QEMU process.

CVE-2015-4037

    Kurt Seifried of Red Hat Product Security discovered that QEMU's
    user mode networking stack uses predictable temporary file names
    when the -smb option is used. An unprivileged user can use this flaw
    to cause a denial of service.

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.1.2+dfsg-6+deb7u8.

We recommend that you upgrade your qemu-kvm packages.
