Upgrade Alpine:3.11 unzip to version 6.0-r1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream unzip package and not the unzip package as distributed by Alpine. See How to fix? for Alpine:3.11 relevant fixed versions and status.

Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive, possibly related to an Extra-Field size value.
