CVE-2016-2197 1 Qemu 1 Qemu 2024-08-05 5.5 Medium
QEMU (aka Quick Emulator) built with an IDE AHCI emulation support is vulnerable to a null pointer dereference flaw. It occurs while unmapping the Frame Information Structure (FIS) and Command List Block (CLB) entries. A privileged user inside guest could use this flaw to crash the QEMU process instance resulting in DoS.
CVE-2016-2198 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-05 5.5 Medium
QEMU (aka Quick Emulator) built with the USB EHCI emulation support is vulnerable to a null pointer dereference flaw. It could occur when an application attempts to write to EHCI capabilities registers. A privileged user inside quest could use this flaw to crash the QEMU process instance resulting in DoS.
CVE-2016-1981 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2024-08-05 5.5 Medium
QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing data via transmit or receive descriptors, provided the initial receive/transmit descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS.
CVE-2016-1922 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-05 5.5 Medium
QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue.
CVE-2016-1714 3 Oracle, Qemu, Redhat 4 Linux, Qemu, Enterprise Linux and 1 more 2024-08-05 N/A
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-2016-1568 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2024-08-05 8.8 High
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.
CVE-2017-18030 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-05 4.4 Medium
The cirrus_invalidate_region function in hw/display/cirrus_vga.c in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds array access and QEMU process crash) via vectors related to negative pitch.
CVE-2017-18043 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2024-08-05 N/A
Integer overflow in the macro ROUND_UP (n, d) in Quick Emulator (Qemu) allows a user to cause a denial of service (Qemu process crash).
CVE-2017-17381 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-05 6.5 Medium
The Virtio Vring implementation in QEMU allows local OS guest users to cause a denial of service (divide-by-zero error and QEMU process crash) by unsetting vring alignment while updating Virtio rings.
CVE-2017-16845 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2024-08-05 10.0 Critical
hw/input/ps2.c in Qemu does not validate 'rptr' and 'count' values during guest migration, leading to out-of-bounds access.
CVE-2017-15289 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-08-05 6.0 Medium
The mode4and5 write functions in hw/display/cirrus_vga.c in Qemu allow local OS guest privileged users to cause a denial of service (out-of-bounds write access and Qemu process crash) via vectors related to dst calculation.
CVE-2017-15268 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-08-05 N/A
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.
CVE-2017-15124 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-08-05 N/A
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. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host.
CVE-2017-15119 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2024-08-05 N/A
The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS.
CVE-2017-15118 3 Canonical, Qemu, Redhat 4 Ubuntu Linux, Qemu, Enterprise Linux and 1 more 2024-08-05 N/A
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.
CVE-2017-15038 1 Qemu 1 Qemu 2024-08-05 N/A
Race condition in the v9fs_xattrwalk function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS users to obtain sensitive information from host heap memory via vectors related to reading extended attributes.
CVE-2017-14167 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Enterprise Linux and 1 more 2024-08-05 8.8 High
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.
CVE-2017-13711 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Enterprise Linux and 1 more 2024-08-05 7.5 High
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.
