-
Several vulnerabilities were discovered in qemu, 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, 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-2015-7549
Qinghao Tang of Qihoo 360 Inc. and Ling Liu of Qihoo 360 Inc. discovered that the PCI MSI-X emulator is vulnerable to a null pointer dereference issue, that could lead to denial-of-service (via application crash).
- 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-2015-8550
Felix Wilhelm of ERNW Research discovered that the PV backend drivers are vulnerable to double fetch vulnerabilities, possibly resulting in arbitrary code execution.
- 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-2015-8567
CVE-2015-8568
Qinghao Tang of Qihoo 360 Inc. discovered that the vmxnet3 device emulator could be used to intentionally leak host memory, thus resulting in denial-of-service.
- CVE-2015-8613
Qinghao Tang of Qihoo 360 Inc. discovered that the SCSI MegaRAID SAS HBA emulation support is vulnerable to a stack-based buffer overflow issue, that could lead to denial-of-service (via application crash).
- CVE-2015-8619
Ling Liu of Qihoo 360 Inc. discovered that the Human Monitor Interface support is vulnerable to an out-of-bound write access issue that could result in denial-of-service (via application crash).
- 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-2015-8744
The vmxnet3 driver incorrectly processes small packets, which could result in denial-of-service (via application crash).
- CVE-2015-8745
The vmxnet3 driver incorrectly processes Interrupt Mask Registers, which could result in denial-of-service (via application crash).
- 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).
- CVE-2016-1981
The e1000 driver is vulnerable to an infinite loop issue that could lead to denial-of-service (via application crash).
For the stable distribution (jessie), these problems have been fixed in version 1:2.1+dfsg-12+deb8u5a.
We recommend that you upgrade your qemu packages.
