CVE-2019-12929: Qemu

Critical severity, CVSS 9.8. EPSS: 4.9% chance of exploitation in the next 30 days.

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

Affected products

• Qemu Qemu: up to and including 4.0.0
