AI-suggested

Upgrade adm-zip to version 0.6.1 or later, where the vulnerability is fixed by masking out setuid, setgid, and sticky bits during extraction. Avoid using the keepOriginalPermission=true flag when extracting untrusted ZIP archives, especially in root or privileged contexts. If upgrading immediately is not possible, do not extract untrusted ZIP files as root with this flag enabled.

Description

adm-zip versions prior to 0.6.1 have a vulnerability where extraction with the keepOriginalPermission=true flag preserves setuid/setgid bits from untrusted ZIP files. When extraction is performed as root, this can lead to local privilege escalation by creating root-owned setuid binaries that execute attacker-controlled code with elevated privileges.
