How to fix?

Upgrade Alpine:3.11 unzip to version 6.0-r3 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.

Heap-based buffer overflow in the test_compr_eb function in Info-ZIP UnZip 6.0 and earlier allows remote attackers to execute arbitrary code via a crafted zip file in the -t command argument to the unzip command.
