Debian Security Advisory DSA-3348-1 email@example.com
https://www.debian.org/security/ Salvatore Bonaccorso

Package : qemu
CVE ID : CVE-2015-3214 CVE-2015-5154 CVE-2015-5165 CVE-2015-5225
Debian Bug : 793811 794610 795087 795461 796465
Several vulnerabilities were discovered in qemu, a fast processor
Matt Tait of Google’s Project Zero security team discovered a flaw
in the QEMU i8254 PIT emulation. A privileged guest user in a guest
with QEMU PIT emulation enabled could potentially use this flaw to
execute arbitrary code on the host with the privileges of the
hosting QEMU process.
Kevin Wolf of Red Hat discovered a heap buffer overflow flaw in the
IDE subsystem in QEMU while processing certain ATAPI commands. A
privileged guest user in a guest with the CDROM drive enabled could
potentially use this flaw to execute arbitrary code on the host with
the privileges of the hosting QEMU process.
Donghai Zhu discovered that the QEMU model of the RTL8139 network
card did not sufficiently validate inputs in the C+ mode offload
emulation, allowing a malicious guest to read uninitialized memory
from the QEMU process’s heap.
Mr Qinghao Tang from QIHU 360 Inc. and Mr Zuozhi from Alibaba Inc
discovered a buffer overflow flaw in the VNC display driver leading
to heap memory corruption. 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.
A buffer overflow vulnerability was discovered in the way QEMU
handles the virtio-serial device. A malicious guest 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+deb7u9. The oldstable distribution is only
affected by CVE-2015-5165 and CVE-2015-5745.
For the stable distribution (jessie), these problems have been fixed in
For the unstable distribution (sid), these problems have been fixed in
We recommend that you upgrade your qemu packages.
