| qemu_deliver_packet_iov in net/net.c in Qemu accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact. | |||||
| CVE-2018-17962 | 6 Canonical, Debian, Oracle and 3 more | 6 Ubuntu Linux, Debian Linux, Linux and 3 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |

| 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. | |||||
| CVE-2018-16847 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2024-11-21 | 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-2018-15746 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| qemu-seccomp.c in QEMU might allow local OS guest users to cause a denial of service (guest crash) by leveraging mishandling of the seccomp policy for threads other than the main thread. | |||||
| CVE-2018-12617 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket. | |||||
