---|---|---|---|---|---|---|
2018-07-03 | CVE-2017-2615 | Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. | Xenserver, Debian_linux, Qemu, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_workstation, Openstack, Xen | 9.1 | ||
2018-07-09 | CVE-2017-7471 | Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System (9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing files on a shared host directory. A privileged user inside guest could use this flaw to access host file system beyond the shared folder and potentially escalating their privileges on a host. | Qemu | 9.0 | ||
2018-07-26 | CVE-2017-7539 | An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. | Qemu, Openstack, Virtualization | 7.5 | ||
2018-10-16 | CVE-2018-10839 | Qemu emulator <= 3.0.0 built with the NE2000 NIC emulation support is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network. A user inside guest could use this flaw to crash the Qemu process resulting in DoS. | Ubuntu_linux, Debian_linux, Qemu | 6.5 | ||
2019-02-19 | CVE-2019-3812 | 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. | Ubuntu_linux, Fedora, Leap, Qemu | 5.5 | ||
2021-01-28 | CVE-2020-35517 | A flaw was found in qemu. A host privilege escalation issue was found in the virtio-fs shared file system daemon where a privileged guest user is able to create a device special file in the shared directory and use it to r/w access host devices. | Qemu | 8.2 | ||
2021-03-18 | CVE-2021-3416 | A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the host resulting in DoS scenario. | Debian_linux, Fedora, Qemu, Enterprise_linux | 6.0 | ||
2021-05-06 | CVE-2021-3507 | A heap buffer overflow was found in the floppy disk emulator of QEMU up to 6.0.0 (including). It could occur in fdctrl_transfer_handler() in hw/block/fdc.c while processing DMA read data transfers from the floppy drive to the guest system. A privileged guest user could use this flaw to crash the QEMU process on the host resulting in DoS scenario, or potential information leakage from the host memory. | Debian_linux, Qemu, Enterprise_linux | 6.1 | ||
2021-05-26 | CVE-2021-20196 | A NULL pointer dereference flaw was found in the floppy disk emulator of QEMU. This issue occurs while processing read/write ioport commands if the selected floppy drive is not initialized with a block device. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | Debian_linux, Qemu | 6.5 | ||
2022-03-16 | CVE-2021-20257 | 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. | Debian_linux, Fedora, Qemu, Codeready_linux_builder, Enterprise_linux, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_power_little_endian, Openstack_platform | 6.5 |
