Package : qemu
CVE ID : CVE-2015-3214 CVE-2015-5154 CVE-2015-5165 CVE-2015-5225
CVE-2015-5745
Debian Bug : 793811 794610 795087 795461 796465
Several vulnerabilities were discovered in qemu, a fast processor
emulator.
CVE-2015-3214
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.
CVE-2015-5154
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.
CVE-2015-5165
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.
CVE-2015-5225
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.
CVE-2015-5745
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
version 1:2.1+dfsg-12+deb8u2.
For the unstable distribution (sid), these problems have been fixed in
version 1:2.4+dfsg-1a.
We recommend that you upgrade your qemu packages.
