UBUNTU-CVE-2016-5338
The 1 espregread and 2 espregwrite functions in hw/scsi/esp.c in QEMU allow local guest OS administrators to cause a denial of service QEMU process crash or execute arbitrary code on the QEMU host via vectors related to the information transfer buffer...
qemu: incorrect banked access bounds checking in vga module
An out-of-bounds read/write access flaw was found in the way QEMU's VGA emulation with VESA BIOS Extensions VBE support performed read/write operations using I/O port methods. A privileged guest user could use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU...
DEBIAN-CVE-2016-3710
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue...
