| CVE-2020-14394 | 3 Fedoraproject, Qemu, Redhat | 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more | 2024-08-04 | 3.2 Low |
| An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service. | ||||
| CVE-2020-14364 | 6 Canonical, Debian, Fedoraproject and 3 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2024-08-04 | 5.0 Medium |
| An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. | ||||
| CVE-2020-13791 | 1 Qemu | 1 Qemu | 2024-08-04 | 5.5 Medium |

| CVE-2020-13800 | 3 Canonical, Opensuse, Qemu | 3 Ubuntu Linux, Leap, Qemu | 2024-08-04 | 6.0 Medium |
| ati-vga in hw/display/ati.c in QEMU 4.2.0 allows guest OS users to trigger infinite recursion via a crafted mm_index value during an ati_mm_read or ati_mm_write call. | ||||
| CVE-2020-13754 | 4 Canonical, Debian, Qemu and 1 more | 5 Ubuntu Linux, Debian Linux, Qemu and 2 more | 2024-08-04 | 6.7 Medium |
| hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation. | ||||
| CVE-2020-13765 | 4 Canonical, Debian, Qemu and 1 more | 4 Ubuntu Linux, Debian Linux, Qemu and 1 more | 2024-08-04 | 5.6 Medium |
| rom_copy() in hw/core/loader.c in QEMU 4.0 and 4.1.0 does not validate the relationship between two addresses, which allows attackers to trigger an invalid memory copy operation. | ||||
| CVE-2020-13659 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-08-04 | 2.5 Low |
| address_space_map in exec.c in QEMU 4.2.0 can trigger a NULL pointer dereference related to BounceBuffer. | ||||
| CVE-2020-13362 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-08-04 | 3.2 Low |
| In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a crafted reply_queue_head field from a guest OS user. | ||||
| CVE-2020-13361 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-08-04 | 3.9 Low |
| In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation. | ||||
| CVE-2020-13253 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2024-08-04 | 5.5 Medium |
| 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 | 2024-08-04 | 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-2020-11869 | 1 Qemu | 1 Qemu | 2024-08-04 | 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-2020-11947 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2024-08-04 | 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-2020-11102 | 1 Qemu | 1 Qemu | 2024-08-04 | 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 | 5 Ubuntu Linux, Leap, Qemu and 2 more | 2024-08-04 | 5 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 | 2 Qemu, Redhat | 2 Qemu, Advanced Virtualization | 2024-08-04 | 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 | 2 Qemu, Redhat | 2 Qemu, Advanced Virtualization | 2024-08-04 | 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-2020-7211 | 4 Libslirp Project, Microsoft, Qemu and 1 more | 4 Libslirp, Windows, Qemu and 1 more | 2024-08-04 | 7.5 High |
| tftp.c in libslirp 4.1.0, as used in QEMU 4.2.0, does not prevent ..\ directory traversal on Windows. | ||||
