CVE-2023-32684 DetailDescriptionLima launches Linux virtual machines, typically on macOS, for running containerd. Prior to version 0.16.0, a virtual machine instance with a malicious disk image could read a single file on the host filesystem, even when no filesystem is mounted from the host. The official templates of Lima and the well-known third party products (Colima, Rancher Desktop, and Finch) are unlikely to be affected by this issue. To exploit this issue, the attacker has to embed the target file path (an absolute or a relative path from the instance directory) in a malicious disk image, as the qcow2 (or vmdk) backing file path string. As Lima refuses to run as the root, it is practically impossible for the attacker to read the entire host disk via `/dev/rdiskN`. Also, practically, the attacker cannot read at least the first 512 bytes (MBR) of the target file. The issue has been patched in Lima in version 0.16.0 by prohibiting using a backing file path in the VM base image. Severity
CVSS 3.x Severity and Metrics:
NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA. Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
