What is CVE-2024-24579?
CVE-2024-24579 is a medium-severity path traversal vulnerability in anchore stereoscope, published on 31 Jan 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-22
