Package : qemu
Version : 1.1.2+dfsg-6+deb7u14
CVE ID : CVE-2015-5239 CVE-2016-2857 CVE-2016-4020 CVE-2016-4439
CVE-2016-5403 CVE-2016-6351
Multiple vulnerabilities have been discovered in QEMU, a fast processor
emulator. The Common Vulnerabilities and Exposures project identifies
the following problems:
CVE-2015-5239
Lian Yihan discovered that QEMU incorrectly handled certain payload
messages in the VNC display driver. A malicious guest could use this
issue to cause the QEMU process to hang, resulting in a denial of
service.
CVE-2016-2857
Ling Liu discovered that QEMU incorrectly handled IP checksum
routines. An attacker inside the guest could use this issue to cause
QEMU to crash, resulting in a denial of service, or possibly leak
host memory bytes.
CVE-2016-4020
Donghai Zdh discovered that QEMU incorrectly handled the Task
Priority Register(TPR). A privileged attacker inside the guest could
use this issue to possibly leak host memory bytes.
CVE-2016-4439, CVE-2016-6351
Li Qiang disovered that the emulation of the 53C9X Fast SCSI
Controller is affected by out of bound access issues.
CVE-2016-5403
Zhenhao Hong discovered that a malicious guest administrator can
cause unbounded memory allocation in QEMU (which can cause an
Out-of-Memory condition) by submitting virtio requests without
bothering to wait for completion.
For Debian 7 "Wheezy", these problems have been fixed in version
1.1.2+dfsg-6+deb7u14.
We recommend that you upgrade your qemu packages.
