CVE-2019-12929 (CCN-162866)

Assigned:2019-06-06
Published:2019-06-06
Updated:2020-08-24
Summary:** 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.
