| CVE-2018-16872 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 3.5 LOW | 5.3 MEDIUM |
| A flaw was found in qemu Media Transfer Protocol (MTP). The code opening files in usb_mtp_get_object and usb_mtp_get_partial_object and directories in usb_mtp_object_readdir doesn't consider that the underlying filesystem may have changed since the time lstat(2) was called in usb_mtp_object_alloc, a classical TOCTTOU problem. An attacker with write access to the host filesystem shared with a guest can use this property to navigate the host filesystem in the context of the QEMU process and read any file the QEMU process has access to. Access to the filesystem may be local or via a network share protocol such as CIFS. | |||||
| CVE-2018-16867 | 3 Canonical, Fedoraproject, Qemu | 3 Ubuntu Linux, Fedora, Qemu | 2024-11-21 | 4.4 MEDIUM | 7.8 HIGH |
| A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS scenario OR possibly lead to code execution on the host. | |||||

| 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-2017-15124 | 1 Qemu | 1 Qemu | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| 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 | 4 Ubuntu Linux, Debian Linux, Qemu and 1 more | 2024-11-21 | 5.0 MEDIUM | 5.8 MEDIUM |
| 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 | 3 Ubuntu Linux, Qemu, Enterprise Linux | 2024-11-21 | 7.5 HIGH | 8.3 HIGH |
| 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-2016-9603 | 4 Citrix, Debian, Qemu and 1 more | 9 Xenserver, Debian Linux, Qemu and 6 more | 2024-11-21 | 9.0 HIGH | 5.5 MEDIUM |
