Vulnerability details
The vulnerability allows a remote attacker to write arbitrary files on the host.
The vulnerability exists due to path traversal in the OCI layer tarball extraction logic in boxlite/src/images/archive/tar.rs when processing a crafted OCI image containing symlink tar entries that point outside the extraction root. A remote attacker can supply a specially crafted OCI image to write arbitrary files on the host.
User interaction is required because a victim must load the malicious image.
