CWE-22 · CNA: redhat · CVSS v3.1 · 3 references · NVD status: Awaiting Analysis

Description

A flaw was found in the buildah/copier Go package. When used outside of Buildah by a non-root caller, a crafted tar archive containing malicious symlinks can escape the target extraction directory and create files outside the intended destination. Buildah itself uses chroot hardening and is not affected.
