CVE-2020-10761 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2020-11-10 4.0 MEDIUM 5.0 MEDIUM
An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service.

CVE-2017-10806 2 Debian, Qemu 2 Debian Linux, Qemu 2020-11-10 2.1 LOW 5.5 MEDIUM
Stack-based buffer overflow in hw/usb/redirect.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (QEMU process crash) via vectors related to logging debug messages.
CVE-2017-5898 2 Qemu, Suse 5 Qemu, Linux Enterprise Desktop, Linux Enterprise Server and 2 more 2020-11-10 2.1 LOW 5.5 MEDIUM
Integer overflow in the emulated_apdu_from_guest function in usb/dev-smartcard-reader.c in Quick Emulator (Qemu), when built with the CCID Card device emulator support, allows local users to cause a denial of service (application crash) via a large Application Protocol Data Units (APDU) unit.
CVE-2017-9060 1 Qemu 1 Qemu 2020-11-10 4.9 MEDIUM 5.5 MEDIUM
Memory leak in the virtio_gpu_set_scanout function in hw/display/virtio-gpu.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (memory consumption) via a large number of "VIRTIO_GPU_CMD_SET_SCANOUT:" commands.
CVE-2018-7858 4 Canonical, Opensuse, Qemu and 1 more 9 Ubuntu Linux, Leap, Qemu and 6 more 2020-11-10 2.1 LOW 5.5 MEDIUM
Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display.
CVE-2016-9846 1 Qemu 1 Qemu 2020-11-10 4.9 MEDIUM 6.5 MEDIUM
QEMU (aka Quick Emulator) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while updating the cursor data in update_cursor_data_virgl. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.
CVE-2016-7909 2 Debian, Qemu 2 Debian Linux, Qemu 2020-11-10 4.9 MEDIUM 4.4 MEDIUM
The pcnet_rdra_addr function in hw/net/pcnet.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by setting the (1) receive or (2) transmit descriptor ring length to 0.
CVE-2015-8701 1 Qemu 1 Qemu 2020-11-10 2.1 LOW 6.5 MEDIUM
QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue.
CVE-2017-15289 1 Qemu 1 Qemu 2020-11-10 2.1 LOW 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-2016-1922 2 Debian, Qemu 2 Debian Linux, Qemu 2020-11-10 2.1 LOW 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.
