CVE-2016-4952: Out-of-bounds access issue in pvsci_ring_init_msg/data routines (bsc#981276). - CVE-2014-3672: The qemu implementation in libvirt Xen allowed local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr (bsc#981264). - CVE-2016-4441: The get_cmd function in the 53C9X Fast SCSI Controller (FSC) support did not properly check DMA length, which allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command (bsc#980724). - CVE-2016-4439: The esp_reg_write function in the 53C9X Fast SCSI Controller (FSC) support did not properly check command buffer length, which allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the host via unspecified vectors (bsc#980716). - CVE-2016-3710: The VGA module improperly performed bounds checking on banked access to video memory, which allowed 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 (bsc#978164). - CVE-2016-3960: Integer overflow in the x86 shadow pagetable code allowed local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping (bsc#974038). - CVE-2016-3159: The fpu_fxrstor function in arch/x86/i387.c did not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allowed local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits (bsc#973188). - CVE-2016-3158: The xrstor function did not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allowed local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits (bsc#973188). - CVE-2016-4037: The ehci_advance_state function in hw/usb/hcd-ehci.c allowed local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular split isochronous transfer descriptor (siTD) list (bsc#976111). - CVE-2016-4020: The patch_instruction function did not initialize the imm32 variable, which allowed local guest OS administrators to obtain sensitive information from host stack memory by accessing the Task Priority Register (TPR) (bsc#975907). -
