What is CVE-2019-12929?
CVE-2019-12929 is a critical command injection vulnerability in Qemu Qemu, published on 24 Jun 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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
