What is CVE-2024-4467?
A vulnerability exists in the QEMU disk image utility related to the 'info' command, where a specially crafted image file containing a specific JSON value can cause the qemu-img process to use an excessive amount of system resources. This behavior may result in resource exhaustion, potentially leading to a denial of service. The exploit can also enable unauthorized read/write access to existing external files on the host system, creating a significant security risk for affected environments.
