The (1) fw_cfg_write and (2) fw_cfg_read functions in hw/nvram/fw_cfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAP_SYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration.

CVE-2015-7549 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Qinghao Tang discovered that QEMU incorrectly handled PCI MSI-X support. An
attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS
and Ubuntu 15.10. (CVE-2015-7549)
Lian Yihan discovered that QEMU incorrectly handled the VNC server. A
remote attacker could use this issue to cause QEMU to crash, resulting in a
denial of service. (CVE-2015-8504)
Felix Wilhelm discovered a race condition in the Xen paravirtualized
drivers which can cause double fetch vulnerabilities. An attacker in the
paravirtualized guest could exploit this flaw to cause a denial of service
(crash the host) or potentially execute arbitrary code on th

Qemu: nvram: OOB r/w access in processing firmware configurations
The (1) fw_cfg_write and (2) fw_cfg_read functions in hw/nvram/fw_cfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAP_SYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration.
An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process.

CVE-2016-4009 python-pillow: integer overflow in the ImagingResampleHorizontal function
Integer overflow in the ImagingResampleHorizontal function in
libImaging/Resample.c in Pillow before 3.1.1 allows remote attackers to have
unspecified impact via negative values of the new size, which triggers a
heap-based buffer overflow.

CVE-2016-1714 Qemu: nvram: OOB r/w access in processing firmware configurations
Qemu emulator built with the Firmware Configuration device emulation support is
vulnerable to an OOB r/w access issue. It could occur while processing firmware
configurations, if the current configuration entry value was set to be
invalid(FW_CFG_INVALID=0xffff).
A privileged(CAP_SYS_RAWIO) user/process inside guest could use this flaw to
crash the Qemu process instance resulting in DoS OR potentially execute
arbitrary code with privileges of the Qemu process on the host.
