| 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. | ||||
| CVE-2020-7039 | 5 Debian, Libslirp Project, Opensuse and 2 more | 12 Debian Linux, Libslirp, Leap and 9 more | 2024-08-04 | 5.6 Medium |
| tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code. | ||||
| CVE-2020-1711 | 4 Debian, Opensuse, Qemu and 1 more | 9 Debian Linux, Leap, Qemu and 6 more | 2024-08-04 | 7.7 High |
| 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-2021-20295 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-08-03 | 6.5 Medium |
| It was discovered that the update for the virt:rhel module in the RHSA-2020:4676 (https://access.redhat.com/errata/RHSA-2020:4676) erratum released as part of Red Hat Enterprise Linux 8.3 failed to include the fix for the qemu-kvm component issue CVE-2020-10756, which was previously corrected in virt:rhel/qemu-kvm via erratum RHSA-2020:4059 (https://access.redhat.com/errata/RHSA-2020:4059). CVE-2021-20295 was assigned to that Red Hat specific security regression. For more details about the original security issue CVE-2020-10756, refer to bug 1835986 or the CVE page: https://access.redhat.com/security/cve/CVE-2020-10756. | ||||
| CVE-2021-20263 | 1 Qemu | 1 Qemu | 2024-08-03 | 3.3 Low |
| A flaw was found in the virtio-fs shared file system daemon (virtiofsd) of QEMU. The new 'xattrmap' option may cause the 'security.capability' xattr in the guest to not drop on file write, potentially leading to a modified, privileged executable in the guest. In rare circumstances, this flaw could be used by a malicious user to elevate their privileges within the guest. | ||||
| CVE-2021-20255 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-08-03 | 5.5 Medium |
| A stack overflow via an infinite recursion vulnerability was found in the eepro100 i8255x device emulator of QEMU. This issue occurs while processing controller commands due to a DMA reentry issue. This flaw allows a guest user or process to consume CPU cycles or crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-20257 | 4 Debian, Fedoraproject, Qemu and 1 more | 9 Debian Linux, Fedora, Qemu and 6 more | 2024-08-03 | 6.5 Medium |
| An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | ||||
