Several vulnerabilities were discovered in qemu-kvm, a full
virtualization solution on x86 hardware.
CVE-2015-7295
Jason Wang of Red Hat Inc. discovered that the Virtual Network
Device support is vulnerable to denial-of-service (via resource
exhaustion), that could occur when receiving large packets.
CVE-2015-7504
Qinghao Tang of Qihoo 360 Inc. and Ling Liu of Qihoo 360 Inc.
discovered that the PC-Net II ethernet controller is vulnerable to
a heap-based buffer overflow that could result in
denial-of-service (via application crash) or arbitrary code
execution.
CVE-2015-7512
Ling Liu of Qihoo 360 Inc. and Jason Wang of Red Hat Inc.
discovered that the PC-Net II ethernet controller is vulnerable to
a buffer overflow that could result in denial-of-service (via
application crash) or arbitrary code execution.
CVE-2015-8345
Qinghao Tang of Qihoo 360 Inc. discovered that the eepro100
emulator contains a flaw that could lead to an infinite loop when
processing Command Blocks, eventually resulting in
denial-of-service (via application crash).
CVE-2015-8504
Lian Yihan of Qihoo 360 Inc. discovered that the VNC display
driver support is vulnerable to an arithmetic exception flaw that
could lead to denial-of-service (via application crash).
CVE-2015-8558
Qinghao Tang of Qihoo 360 Inc. discovered that the USB EHCI
emulation support contains a flaw that could lead to an infinite
loop during communication between the host controller and a device
driver. This could lead to denial-of-service (via resource
exhaustion).
CVE-2015-8743
Ling Liu of Qihoo 360 Inc. discovered that the NE2000 emulator is
vulnerable to an out-of-bound read/write access issue, potentially
resulting in information leak or memory corruption.
CVE-2016-1568
Qinghao Tang of Qihoo 360 Inc. discovered that the IDE AHCI
emulation support is vulnerable to a use-after-free issue, that
could lead to denial-of-service (via application crash) or
arbitrary code execution.
CVE-2016-1714
Donghai Zhu of Alibaba discovered that the Firmware Configuration
emulation support is vulnerable to an out-of-bound read/write
access issue, that could lead to denial-of-service (via
application crash) or arbitrary code execution.
CVE-2016-1922
Ling Liu of Qihoo 360 Inc. discovered that 32-bit Windows guests
support is vulnerable to a null pointer dereference issue, that
could lead to denial-of-service (via application crash).
For the oldstable distribution (wheezy), these problems have been fixed
in version 1.1.2+dfsg-6+deb7u12.
We recommend that you upgrade your qemu-kvm packages.
