## Overview

Versions of astral-tokio-tar prior to 0.6.1 contain a PAX header interpretation
bug that allows manipulated entries to be made selectively visible or invisible
during extraction with astral-tokio-tar versus other tar implementations.
An attacker could use this differential to smuggle unexpected files onto a
victim's filesystem.

## Affected packages

- `astral-tokio-tar >= 0.0.0-0, < 0.6.1`

## Remediation

Upgrade to a patched release:

- `astral-tokio-tar 0.6.1`
