Debian Bug : 798101 799073 799074
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.
