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-6+deb7u11.

We recommend that you upgrade your qemu-kvm packages.");
