| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2016-05-20 | CVE-2016-4439 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The esp_reg_write function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check command buffer length, which allows 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 QEMU host via unspecified vectors. | 4.6 |
| 2016-05-11 | CVE-2016-3712 | Integer Overflow or Wraparound vulnerability in multiple products Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode. | 5.5 |
| 2016-05-11 | CVE-2016-3710 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products 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. | 7.2 |
| 2016-04-26 | CVE-2016-4002 | Classic Buffer Overflow vulnerability in multiple products Buffer overflow in the mipsnet_receive function in hw/net/mipsnet.c in QEMU, when the guest NIC is configured to accept large packets, allows remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes. | 6.8 |
| 2016-04-12 | CVE-2016-2857 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The net_checksum_calculate function in net/checksum.c in QEMU allows local guest OS users to cause a denial of service (out-of-bounds heap read and crash) via the payload length in a crafted packet. | 8.4 |
| 2016-04-12 | CVE-2016-1568 | Use After Free vulnerability in multiple products Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command. | 8.8 |
| 2016-04-07 | CVE-2016-2858 | Insufficient Entropy vulnerability in multiple products QEMU, when built with the Pseudo Random Number Generator (PRNG) back-end support, allows local guest OS users to cause a denial of service (process crash) via an entropy request, which triggers arbitrary stack based allocation and memory corruption. | 6.5 |
| 2016-04-07 | CVE-2016-1714 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products 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. | 8.1 |
| 2016-01-12 | CVE-2015-1779 | Resource Exhaustion vulnerability in multiple products The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. | 8.6 |
| 2016-01-08 | CVE-2015-7512 | Classic Buffer Overflow vulnerability in multiple products Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet. | 9.0 |
