A flaw was found in the containers/storage library. A crafted tar archive containing a malicious whiteout header (e.g. victim/.wh.) can cause the extraction destination directory to be replaced with an arbitrary file when processed by storage/pkg/archive.UnpackLayer, ApplyLayer, or ApplyUncompressedLayer.
Why it matters
- ▸ Requires local access, limiting mass exploitation
- ▸ Low attack complexity — no special conditions needed to exploit
- ▸ No authentication required
- ▸ Requires the victim to take an action (e.g. open a file or link)
Apply the vendor patch as soon as it's available or already released. User-awareness training reduces risk here, since exploitation depends on tricking a user into acting.
This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.

EUVD is ENISA's EU vulnerability database, still in beta. EPSS is a probabilistic exploitation-likelihood score, not a certainty.
