    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.
