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 | ||||
CVE-2019-12928 | 1 Qemu | 1 Qemu | 2024-11-21 | N/A |
The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote 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 | ||||
CVE-2019-12247 | 1 Qemu | 1 Qemu | 2024-11-21 | N/A |
QEMU 3.0.0 has an Integer Overflow because the qga/commands*.c files do not check the length of the argument list or the number of environment variables. NOTE: This has been disputed as not exploitable | ||||
CVE-2019-12155 | 2 Qemu, Redhat | 5 Qemu, Advanced Virtualization, Enterprise Linux and 2 more | 2024-11-21 | N/A |
interface_release_resource in hw/display/qxl.c in QEMU 3.1.x through 4.0.0 has a NULL pointer dereference. | ||||
CVE-2019-12068 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 3.8 Low |
In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well. | ||||
CVE-2019-12067 | 4 Debian, Fedoraproject, Qemu and 1 more | 5 Debian Linux, Fedora, Qemu and 2 more | 2024-11-21 | 6.5 Medium |
The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL dereference) when the command header 'ad->cur_cmd' is null. | ||||
CVE-2018-7858 | 4 Canonical, Opensuse, Qemu and 1 more | 11 Ubuntu Linux, Leap, Qemu and 8 more | 2024-11-21 | 5.5 Medium |
Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display. | ||||
CVE-2018-7550 | 4 Canonical, Debian, Qemu and 1 more | 11 Ubuntu Linux, Debian Linux, Qemu and 8 more | 2024-11-21 | 8.8 High |
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access. | ||||
CVE-2018-5683 | 4 Canonical, Debian, Qemu and 1 more | 11 Ubuntu Linux, Debian Linux, Qemu and 8 more | 2024-11-21 | 6.0 Medium |
The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation. | ||||
CVE-2018-20815 | 2 Qemu, Redhat | 4 Qemu, Enterprise Linux, Openstack and 1 more | 2024-11-21 | N/A |
In QEMU 3.1.0, load_device_tree in device_tree.c calls the deprecated load_image function, which has a buffer overflow risk. | ||||
CVE-2018-20216 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2024-11-21 | 7.5 High |
QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and -1 is mishandled). | ||||
CVE-2018-20191 | 3 Canonical, Fedoraproject, Qemu | 3 Ubuntu Linux, Fedora, Qemu | 2024-11-21 | 7.5 High |
hw/rdma/vmw/pvrdma_main.c in QEMU does not implement a read operation (such as uar_read by analogy to uar_write), which allows attackers to cause a denial of service (NULL pointer dereference). | ||||
CVE-2018-20126 | 3 Canonical, Opensuse, Qemu | 3 Ubuntu Linux, Leap, Qemu | 2024-11-21 | 5.5 Medium |
hw/rdma/vmw/pvrdma_cmd.c in QEMU allows create_cq and create_qp memory leaks because errors are mishandled. | ||||
CVE-2018-20125 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2024-11-21 | 7.5 High |
hw/rdma/vmw/pvrdma_cmd.c in QEMU allows attackers to cause a denial of service (NULL pointer dereference or excessive memory allocation) in create_cq_ring or create_qp_rings. | ||||
CVE-2018-20124 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2024-11-21 | 5.5 Medium |
