CVE-2020-12829 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2024-11-21 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 2 Qemu, Redhat 3 Qemu, Advanced Virtualization, Enterprise Linux 2024-11-21 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 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 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 2024-11-21 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 2024-11-21 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 2024-11-21 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 2 Qemu, Redhat 4 Qemu, Enterprise Linux, Openstack and 1 more 2024-11-21 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-2019-8934 2 Opensuse, Qemu 2 Leap, Qemu 2024-11-21 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 5 Canonical, Fedoraproject, Opensuse and 2 more 7 Ubuntu Linux, Fedora, Leap and 4 more 2024-11-21 N/A
In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow.
CVE-2019-6501 3 Fedoraproject, Qemu, Redhat 5 Fedora, Qemu, Enterprise Linux and 2 more 2024-11-21 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 2024-11-21 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-2019-3812 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2024-11-21 N/A
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 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 5 Canonical, Debian, Opensuse and 2 more 7 Ubuntu Linux, Debian Linux, Leap and 4 more 2024-11-21 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 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 3 Libslirp Project, Qemu, Redhat 5 Libslirp, Qemu, Advanced Virtualization and 2 more 2024-11-21 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 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 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 N/A
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
