Detailsinfo

A vulnerability has been found in anchore stereoscope and classified as critical. This vulnerability affects the function UntarToDirectory. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

stereoscope is a go library for processing container images and simulating a squash filesystem. Prior to version 0.0.1, it is possible to craft an OCI tar archive that, when stereoscope attempts to unarchive the contents, will result in writing to paths outside of the unarchive temporary directory. Specifically, use of `github.com/anchore/stereoscope/pkg/file.UntarToDirectory()` function, the `github.com/anchore/stereoscope/pkg/image/oci.TarballImageProvider` struct, or the higher level `github.com/anchore/stereoscope/pkg/image.Image.Read()` function express this vulnerability. As a workaround, if you are using the OCI archive as input into stereoscope then you can switch to using an OCI layout by unarchiving the tar archive and provide the unarchived directory to stereoscope.
