| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2018-01-09 | CVE-2017-15124 | Unspecified vulnerability in Qemu VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. | 7.5 |
| 2017-10-16 | CVE-2015-7504 | Out-of-bounds Write vulnerability in multiple products Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. | 8.8 |
| 2017-10-12 | CVE-2017-15268 | Missing Release of Resource after Effective Lifetime vulnerability in Qemu Qemu through 2.10.0 allows remote attackers to cause a memory leak by triggering slow data-channel read operations, related to io/channel-websock.c. | 7.5 |
| 2017-09-08 | CVE-2017-14167 | Integer Overflow or Wraparound vulnerability in multiple products Integer overflow in the load_multiboot function in hw/i386/multiboot.c in QEMU (aka Quick Emulator) allows local guest OS users to execute arbitrary code on the host via crafted multiboot header address values, which trigger an out-of-bounds write. | 8.8 |
| 2017-09-01 | CVE-2017-13711 | Use After Free vulnerability in multiple products Use-after-free vulnerability in the sofree function in slirp/socket.c in QEMU (aka Quick Emulator) allows attackers to cause a denial of service (QEMU instance crash) by leveraging failure to properly clear ifq_so from pending packets. | 7.5 |
| 2017-08-10 | CVE-2014-0145 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Qemu Multiple buffer overflows in QEMU before 1.7.2 and 2.x before 2.0.0, allow local users to cause a denial of service (crash) or possibly execute arbitrary code via a large (1) L1 table in the qcow2_snapshot_load_tmp in the QCOW 2 block driver (block/qcow2-snapshot.c) or (2) uncompressed chunk, (3) chunk length, or (4) number of sectors in the DMG block driver (block/dmg.c). | 7.8 |
| 2017-08-10 | CVE-2014-0143 | Integer Overflow or Wraparound vulnerability in multiple products Multiple integer overflows in the block drivers in QEMU, possibly before 2.0.0, allow local users to cause a denial of service (crash) via a crafted catalog size in (1) the parallels_open function in block/parallels.c or (2) bochs_open function in bochs.c, a large L1 table in the (3) qcow2_snapshot_load_tmp in qcow2-snapshot.c or (4) qcow2_grow_l1_table function in qcow2-cluster.c, (5) a large request in the bdrv_check_byte_request function in block.c and other block drivers, (6) crafted cluster indexes in the get_refcount function in qcow2-refcount.c, or (7) a large number of blocks in the cloop_open function in cloop.c, which trigger buffer overflows, memory corruption, large memory allocations and out-of-bounds read and writes. | 7.0 |
| 2017-08-02 | CVE-2017-10664 | qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt. | 7.5 |
| 2017-07-25 | CVE-2017-7980 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation. | 7.8 |
| 2017-07-06 | CVE-2017-9524 | Improper Input Validation vulnerability in multiple products The qemu-nbd server in QEMU (aka Quick Emulator), when built with the Network Block Device (NBD) Server support, allows remote attackers to cause a denial of service (segmentation fault and server crash) by leveraging failure to ensure that all initialization occurs before talking to a client in the nbd_negotiate function. | 7.5 |
