| 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-2018-20191 | 3 Canonical, Fedoraproject, Qemu | 3 Ubuntu Linux, Fedora, Qemu | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| hw/rdma/vmw/pvrdma_main.c in QEMU does not implement a read operation (such as uar_read by analogy to uar_write), which allows attackers to cause a denial of service (NULL pointer dereference). | |||||
| CVE-2016-9603 | 4 Citrix, Debian, Qemu and 1 more | 9 Xenserver, Debian Linux, Qemu and 6 more | 2023-12-10 | 9.0 HIGH | 9.9 CRITICAL |
| A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. | |||||
| CVE-2017-15118 | 3 Canonical, Qemu, Redhat | 3 Ubuntu Linux, Qemu, Enterprise Linux | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2017-2630 | 1 Qemu | 1 Qemu | 2023-12-10 | 6.5 MEDIUM | 8.8 HIGH |
| A stack buffer overflow flaw was found in the Quick Emulator (QEMU) before 2.9 built with the Network Block Device (NBD) client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process. | |||||
| CVE-2018-20124 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2023-12-10 | 2.1 LOW | 5.5 MEDIUM |
| hw/rdma/rdma_backend.c in QEMU allows guest OS users to trigger out-of-bounds access via a PvrdmaSqWqe ring element with a large num_sge value. | |||||
| CVE-2017-2620 | 5 Citrix, Debian, Qemu and 2 more | 10 Xenserver, Debian Linux, Qemu and 7 more | 2023-12-10 | 9.0 HIGH | 9.9 CRITICAL |
| Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. | |||||
| CVE-2018-16847 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2023-12-10 | 4.6 MEDIUM | 7.8 HIGH |
| An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in nvme device. A guest user/process could use this flaw to crash the QEMU process resulting in DoS or potentially run arbitrary code with privileges of the QEMU process. | |||||
| CVE-2017-7539 | 2 Qemu, Redhat | 4 Qemu, Enterprise Linux, Openstack and 1 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. | |||||

| Qemu emulator <= 3.0.0 built with the NE2000 NIC emulation support is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network. A user inside guest could use this flaw to crash the Qemu process resulting in DoS. | |||||
| CVE-2018-15746 | 1 Qemu | 1 Qemu | 2023-12-10 | 2.1 LOW | 5.5 MEDIUM |
