| sd_wp_addr in hw/sd/sd.c in QEMU 4.2.0 uses an unvalidated address, which leads to an out-of-bounds read during sdhci_write() operations. A guest OS user can crash the QEMU process. | |||||
| CVE-2020-12829 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2024-11-21 | 2.1 LOW | 3.8 LOW |
| In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service. | |||||
| CVE-2020-11947 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 3.8 LOW |
| iscsi_aio_ioctl_cb in block/iscsi.c in QEMU 4.1.0 has a heap-based buffer over-read that may disclose unrelated information from process memory to an attacker. | |||||
| CVE-2020-11869 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 3.3 LOW |
| An integer overflow was found in QEMU 4.0.1 through 4.2.0 in the way it implemented ATI VGA emulation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati-2d.c 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-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 3.1, 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. | |||||
