Path traversal in the ArchiveReader.extractContents() function used by container image load operations allows local attackers to write arbitrary files to any user-writable location on the system by crafting malicious archives with relative pathnames. Public exploit code exists for this vulnerability, and affected users cannot currently patch as fixes are only available in container 0.8.0 and containerization 0.21.0. The vulnerability requires local access and user interaction but carries high severity due to potential for file overwrite and system compromise.
An attacker who controls the registry, a mirror, or the network path to it may be able to serve arbitrary image content in response to a pull by digest, so that a user runs an image other than the one they pinned. The fix compares the returned digest to the pinned digest and fails the pull on a mismatch. Tag pulls are exempt, because a tag is mutable by design. The fix also verifies the hash of manifests and blobs when they are fetched. This vulnerability is addressed in container version 1.6.0 and containerization version 0.52.1.
