CVE-2018-17962 | 6 Canonical, Debian, Oracle and 3 more | 7 Ubuntu Linux, Debian Linux, Linux and 4 more | 2024-08-05 | N/A |
Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used. | ||||
CVE-2018-16847 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2024-08-05 | 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-2018-16867 | 3 Canonical, Fedoraproject, Qemu | 3 Ubuntu Linux, Fedora, Qemu | 2024-08-05 | 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-2018-16872 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-08-05 | 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-2018-15746 | 2 Qemu, Redhat | 4 Qemu, Enterprise Linux, Openstack and 1 more | 2024-08-05 | 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 | 2024-08-05 | 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. | ||||
CVE-2018-11806 | 4 Canonical, Debian, Qemu and 1 more | 12 Ubuntu Linux, Debian Linux, Qemu and 9 more | 2024-08-05 | 8.2 High |
m_cat in slirp/mbuf.c in Qemu has a heap-based buffer overflow via incoming fragmented datagrams. | ||||
CVE-2018-10839 | 4 Canonical, Debian, Qemu and 1 more | 4 Ubuntu Linux, Debian Linux, Qemu and 1 more | 2024-08-05 | N/A |
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-2018-7858 | 4 Canonical, Opensuse, Qemu and 1 more | 11 Ubuntu Linux, Leap, Qemu and 8 more | 2024-08-05 | 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-2018-7550 | 4 Canonical, Debian, Qemu and 1 more | 11 Ubuntu Linux, Debian Linux, Qemu and 8 more | 2024-08-05 | 8.8 High |
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access. | ||||
CVE-2018-5683 | 4 Canonical, Debian, Qemu and 1 more | 11 Ubuntu Linux, Debian Linux, Qemu and 8 more | 2024-08-05 | 6.0 Medium |
The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation. | ||||
CVE-2019-20175 | 1 Qemu | 1 Qemu | 2024-08-05 | 7.5 High |
An issue was discovered in ide_dma_cb() in hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest system can crash the QEMU process in the host system via a special SCSI_IOCTL_SEND_COMMAND. It hits an assertion that implies that the size of successful DMA transfers there must be a multiple of 512 (the size of a sector). NOTE: a member of the QEMU security team disputes the significance of this issue because a "privileged guest user has many ways to cause similar DoS effect, without triggering this assert. | ||||
CVE-2019-20808 | 1 Qemu | 1 Qemu | 2024-08-05 | 6.5 Medium |
In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA implementation. It occurs in the ati_cursor_define() routine while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service. | ||||
CVE-2019-20382 | 5 Canonical, Debian, Opensuse and 2 more | 7 Ubuntu Linux, Debian Linux, Leap and 4 more | 2024-08-05 | 3.5 Low |
QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd. | ||||
CVE-2019-15890 | 3 Libslirp Project, Qemu, Redhat | 5 Libslirp, Qemu, Advanced Virtualization and 2 more | 2024-08-05 | 7.5 High |
libslirp 4.0.0, as used in QEMU 4.1.0, has a use-after-free in ip_reass in ip_input.c. | ||||
CVE-2019-15034 | 1 Qemu | 1 Qemu | 2024-08-05 | 5.8 Medium |
hw/display/bochs-display.c in QEMU 4.0.0 does not ensure a sufficient PCI config space allocation, leading to a buffer overflow involving the PCIe extended config space. | ||||
CVE-2019-12929 | 1 Qemu | 1 Qemu | 2024-08-05 | N/A |
The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue | ||||
CVE-2019-12928 | 1 Qemu | 1 Qemu | 2024-08-05 | N/A |
The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue | ||||
CVE-2019-12247 | 1 Qemu | 1 Qemu | 2024-08-05 | N/A |
QEMU 3.0.0 has an Integer Overflow because the qga/commands*.c files do not check the length of the argument list or the number of environment variables. NOTE: This has been disputed as not exploitable | ||||
CVE-2019-13164 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-08-04 | 7.8 High |
qemu-bridge-helper.c in QEMU 3.1 and 4.0.0 does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass. |
