Description

A path traversal vulnerability has been discovered in podman before version 1.4.0 in the way it handles symlinks inside containers. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container.

• CWE-22Improper Limitation of a Pathname to a Restricted DirectoryThe product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
• CWE-59Improper Link Resolution Before File AccessThe product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
