| CVE-2020-27821 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-11-07 | 6.0 Medium |
| A flaw was found in the memory management API of QEMU during the initialization of a memory region cache. This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial of service. This flaw affects QEMU versions prior to 5.2.0. | ||||
| CVE-2020-27661 | 1 Qemu | 1 Qemu | 2023-11-07 | 6.5 Medium |
| A divide-by-zero issue was found in dwc2_handle_packet in hw/usb/hcd-dwc2.c in the hcd-dwc2 USB host controller emulation of QEMU. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service. | ||||
| CVE-2020-1711 | 4 Debian, Opensuse, Qemu and 1 more | 5 Debian Linux, Leap, Qemu and 2 more | 2023-11-07 | 6.0 Medium |
| An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host. | ||||
| CVE-2020-15863 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2023-11-07 | 5.3 Medium |
| hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555. | ||||
| CVE-2020-14415 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2023-11-07 | 3.3 Low |
| oss_write in audio/ossaudio.c in QEMU before 5.0.0 mishandles a buffer position. | ||||
| CVE-2020-14394 | 3 Fedoraproject, Qemu, Redhat | 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more | 2023-11-07 | 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 | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2023-11-07 | 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-2020-13765 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2023-11-07 | 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-2020-11947 | 1 Qemu | 1 Qemu | 2023-11-07 | 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 | 2023-11-07 | 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-2020-10761 | 4 Canonical, Opensuse, Qemu and 1 more | 4 Ubuntu Linux, Leap, Qemu and 1 more | 2023-11-07 | 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 | 2023-11-07 | 6.5 Medium |
| 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 | 2023-11-07 | 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 | 2023-11-07 | N/A |
| 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-2019-6778 | 4 Canonical, Fedoraproject, Opensuse and 1 more | 4 Ubuntu Linux, Fedora, Leap and 1 more | 2023-11-07 | N/A |
| 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 | 2023-11-07 | N/A |
| 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 | 2023-11-07 | N/A |
| 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-2019-20808 | 1 Qemu | 1 Qemu | 2023-11-07 | 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 | 2023-11-07 | 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-2019-12155 | 1 Qemu | 1 Qemu | 2023-11-07 | N/A |
| interface_release_resource in hw/display/qxl.c in QEMU 3.1.x through 4.0.0 has a NULL pointer dereference. | ||||
