| CVE-2020-11102 | 1 Qemu | 1 Qemu | 2024-11-21 | 6.8 MEDIUM | 5.6 MEDIUM |
| hw/net/tulip.c in QEMU 4.2.0 has a buffer overflow during the copying of tx/rx buffers because the frame size is not validated against the r/w data length. | |||||
| CVE-2020-10761 | 4 Canonical, Opensuse, Qemu and 1 more | 4 Ubuntu Linux, Leap, Qemu and 1 more | 2024-11-21 | 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-2020-10717 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 3.3 LOW |
| A potential DoS flaw was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU version >= v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared directory, a denial of service may occur. This flaw allows a guest user/process to cause this denial of service on the host. | |||||
| CVE-2020-10702 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU. | |||||
| CVE-2019-9824 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| tcp_emu in slirp/tcp_subr.c (aka slirp/src/tcp_subr.c) in QEMU 3.0.0 uses uninitialized data in an snprintf call, leading to Information disclosure. | |||||
| CVE-2019-8934 | 2 Opensuse, Qemu | 2 Leap, Qemu | 2024-11-21 | 2.1 LOW | 3.3 LOW |
| hw/ppc/spapr.c in QEMU through 3.1.0 allows Information Exposure because the hypervisor shares the /proc/device-tree/system-id and /proc/device-tree/model system attributes with a guest. | |||||
| CVE-2019-6778 | 4 Canonical, Fedoraproject, Opensuse and 1 more | 4 Ubuntu Linux, Fedora, Leap and 1 more | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
| In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow. | |||||
| CVE-2019-6501 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| In QEMU 3.1, scsi_handle_inquiry_reply in hw/scsi/scsi-generic.c allows out-of-bounds write and read operations. | |||||
| CVE-2019-5008 | 1 Qemu | 1 Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| hw/sparc64/sun4u.c in QEMU 3.1.50 is vulnerable to a NULL pointer dereference, which allows the attacker to cause a denial of service via a device driver. | |||||
| CVE-2019-3812 | 4 Canonical, Fedoraproject, Opensuse and 1 more | 4 Ubuntu Linux, Fedora, Leap and 1 more | 2024-11-21 | 2.1 LOW | 4.4 MEDIUM |
| QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host. | |||||
| CVE-2019-20808 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 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 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 2.7 LOW | 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-2019-20175 | 1 Qemu | 1 Qemu | 2024-11-21 | 5.0 MEDIUM | 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-2019-15890 | 2 Libslirp Project, Qemu | 2 Libslirp, Qemu | 2024-11-21 | 5.0 MEDIUM | 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 | 2024-11-21 | 4.4 MEDIUM | 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-2019-13164 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 4.6 MEDIUM | 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. | |||||
| CVE-2019-12929 | 1 Qemu | 1 Qemu | 2024-11-21 | 10.0 HIGH | 9.8 CRITICAL |
| 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 | 2024-11-21 | 10.0 HIGH | 9.8 CRITICAL |
| 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 | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2019-12155 | 1 Qemu | 1 Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| interface_release_resource in hw/display/qxl.c in QEMU 3.1.x through 4.0.0 has a NULL pointer dereference. | |||||
