CVE-2022-36648 1 Qemu 1 Qemu 2023-08-26 N/A 10.0 CRITICAL
The hardware emulation in the of_dpa_cmd_add_l2_flood of rocker device model in QEMU, as used in 7.0.0 and earlier, allows remote attackers to crash the host qemu and potentially execute code on the host via execute a malformed program in the guest OS.
CVE-2017-2615 5 Citrix, Debian, Qemu and 2 more 10 Xenserver, Debian Linux, Qemu and 7 more 2021-08-04 9.0 HIGH 9.1 CRITICAL
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.
CVE-2017-2620 5 Citrix, Debian, Qemu and 2 more 10 Xenserver, Debian Linux, Qemu and 7 more 2021-08-04 9.0 HIGH 9.9 CRITICAL
Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process.
CVE-2016-9603 4 Citrix, Debian, Qemu and 1 more 9 Xenserver, Debian Linux, Qemu and 6 more 2021-08-04 9.0 HIGH 9.9 CRITICAL
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
CVE-2018-17963 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2021-08-04 7.5 HIGH 9.8 CRITICAL
qemu_deliver_packet_iov in net/net.c in Qemu accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact.
CVE-2016-4002 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2020-12-14 6.8 MEDIUM 9.8 CRITICAL
Buffer overflow in the mipsnet_receive function in hw/net/mipsnet.c in QEMU, when the guest NIC is configured to accept large packets, allows remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes.
CVE-2016-7161 2 Debian, Qemu 2 Debian Linux, Qemu 2020-11-16 10.0 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in QEMU (aka Quick Emulator) allows attackers to execute arbitrary code on the QEMU host via a large ethlite packet.
CVE-2017-16845 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-09-10 6.4 MEDIUM 10.0 CRITICAL
hw/input/ps2.c in Qemu does not validate 'rptr' and 'count' values during guest migration, leading to out-of-bounds access.
CVE-2017-7471 1 Qemu 1 Qemu 2020-09-10 7.7 HIGH 9.0 CRITICAL
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.
CVE-2015-7512 4 Debian, Oracle, Qemu and 1 more 9 Debian Linux, Linux, Qemu and 6 more 2020-09-09 6.8 MEDIUM 9.0 CRITICAL
Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet.
CVE-2019-12928 1 Qemu 1 Qemu 2020-08-24 10.0 HIGH 9.8 CRITICAL
** DISPUTED ** 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-2019-12929 1 Qemu 1 Qemu 2020-08-24 10.0 HIGH 9.8 CRITICAL
** DISPUTED ** 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-2017-15118 3 Canonical, Qemu, Redhat 3 Ubuntu Linux, Qemu, Enterprise Linux 2019-10-09 7.5 HIGH 9.8 CRITICAL
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.
CVE-2018-20815 1 Qemu 1 Qemu 2019-07-02 7.5 HIGH 9.8 CRITICAL
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-2017-8380 1 Qemu 1 Qemu 2017-09-06 7.5 HIGH 9.8 CRITICAL
Buffer overflow in the "megasas_mmio_write" function in Qemu 2.9.0 allows remote attackers to have unspecified impact via unknown vectors.
CVE-2015-8556 1 Qemu 1 Qemu 2017-03-27 10.0 HIGH 10.0 CRITICAL
Local privilege escalation vulnerability in the Gentoo QEMU package before 2.5.0-r1.
