There is no fixed version for Debian:9 unzip.

NVD Description

Note: Versions mentioned in the description apply only to the upstream unzip package and not the unzip package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

A flaw was found in Unzip. The vulnerability occurs during the conversion of a wide string to a local string that leads to a heap of out-of-bound write. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.
