    Summary: unzip security update

    Details: UnZip is an extraction utility for archives compressed in .zip format. UnZip will list, test, or extract files from a .zip archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract all files into the current directory (and subdirectorie below it) from the specified zipfile. Security Fix(es): A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.(CVE-2021-4217)
