    Several vulnerabilities were discovered in qemu, a fast processor
    emulator.
    
    CVE-2015-5278
    
        Qinghao Tang of QIHU 360 Inc. discovered an infinite loop issue in
        the NE2000 NIC emulation. A privileged guest user could use this
        flaw to mount a denial of service (QEMU process crash).
    
    CVE-2015-5279
    
        Qinghao Tang of QIHU 360 Inc. discovered a heap buffer overflow flaw
        in the NE2000 NIC emulation. A privileged guest user could use this
        flaw to mount a denial of service (QEMU process crash), or
        potentially to execute arbitrary code on the host with the
        privileges of the hosting QEMU process.
    
    CVE-2015-6815
    
        Qinghao Tang of QIHU 360 Inc. discovered an infinite loop issue in
        the e1000 NIC emulation. A privileged guest user could use this flaw
        to mount a denial of service (QEMU process crash).
    
    CVE-2015-6855
    
        Qinghao Tang of QIHU 360 Inc. discovered a flaw in the IDE
        subsystem in QEMU occurring while executing IDE's
        WIN_READ_NATIVE_MAX command to determine the maximum size of a
        drive. A privileged guest user 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-6a+deb7u11.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1:2.1+dfsg-12+deb8u4.
    
    For the testing distribution (stretch), these problems have been fixed
    in version 1:2.4+dfsg-3 or earlier.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1:2.4+dfsg-3 or earlier.
    
    We recommend that you upgrade your qemu packages.
