## Overview

The CPIO extraction functionality doesn't sanitize the paths of the archived files for leading and non-leading `..` which leads in file extraction outside of the current directory. Note, the fixing commit was applied to all affected versions which were re-released.

## Affected packages

- `github.com/sassoftware/go-rpmutils < 0.1.0`

## Remediation

Upgrade to a patched release:

- `github.com/sassoftware/go-rpmutils 0.1.0`
