CVE-2024-24579Tar path traversal in stereoscope when processing OCI tar archives
Medium 5.3
In plain English
A medium-severity path traversal in stereoscope from anchore. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 34% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
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.
