  "details": "### Impact\n\nVersions 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\u0027s filesystem.\n\nSee GHSA-j5gw-2vrg-8fgx for a similar desynchronization bug in astral-tokio-tar.\n\n### Patches\n\nVersions 0.6.1 and newer of astral-tokio-tar address this differential.\n\n### Workarounds\n\nUsers are advised to upgrade to version 0.6.1 or newer to address this advisory.\n\nThere is no workaround other than upgrading. Users should experience no breaking changes as a result of the upgrade.\n\n### Resources\n\n- GHSA-j5gw-2vrg-8fgx is a similar PAX desynchronization bug\n\n### Attribution\n\n- Reporter: Adam Harvey (@lawngnome)",
