GHSA-fp55-jw48-c537 — astral-tokio-tar is Vulnerable to PAX Header Desynchronization

Affected: crates.io: astral-tokio-tar

### Impact

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.

See GHSA-j5gw-2vrg-8fgx for a similar desynchronization bug in astral-tokio-tar.

### Patches

Versions 0.6.1 and newer of astral-tokio-tar address this differential.

### Workarounds

Users are advised to upgrade to version 0.6.1 or newer to address this advisory.

There is no workaround other than upgrading. Users should experience no breaking changes as a result of the upgrade.
