An update for unzip is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1902 Final 1.0 1.0 2022-09-09 Initial 2022-09-09 2022-09-09 openEuler SA Tool V1.0 2022-09-09 unzip security update An update for unzip is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS. 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) An update for unzip is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
