{"id":"OESA-2022-1902","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.\r\n\r\nSecurity Fix(es):\r\n\r\nA 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)","modified":"2026-03-11T06:24:33.387912Z","published":"2022-09-09T11:04:15Z","upstream":["CVE-2021-4217"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2022-1902"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-4217"}],"affected":[{"package":{"name":"unzip","ecosystem":"openEuler:20.03-LTS-SP1","purl":"pkg:rpm/openEuler/unzip&distro=openEuler-20.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0-47.oe1"}]}],"ecosystem_specific":{"aarch64":["unzip-debugsource-6.0-47.oe1.aarch64.rpm","unzip-help-6.0-47.oe1.aarch64.rpm","unzip-6.0-47.oe1.aarch64.rpm","unzip-debuginfo-6.0-47.oe1.aarch64.rpm"],"src":["unzip-6.0-47.oe1.src.rpm"],"x86_64":["unzip-debuginfo-6.0-47.oe1.x86_64.rpm","unzip-6.0-47.oe1.x86_64.rpm","unzip-help-6.0-47.oe1.x86_64.rpm","unzip-debugsource-6.0-47.oe1.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2022-1902.json"}},{"package":{"name":"unzip","ecosystem":"openEuler:20.03-LTS-SP3","purl":"pkg:rpm/openEuler/unzip&distro=openEuler-20.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0-47.oe1"}]}],"ecosystem_specific":{"aarch64":["unzip-help-6.0-47.oe1.aarch64.rpm","unzip-6.0-47.oe1.aarch64.rpm","unzip-debuginfo-6.0-47.oe1.aarch64.rpm","unzip-debugsource-6.0-47.oe1.aarch64.rpm"],"src":["unzip-6.0-47.oe1.src.rpm"],"x86_64":["unzip-debuginfo-6.0-47.oe1.x86_64.rpm","unzip-6.0-47.oe1.x86_64.rpm","unzip-debugsource-6.0-47.oe1.x86_64.rpm","unzip-help-6.0-47.oe1.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2022-1902.json"}},{"package":{"name":"unzip","ecosystem":"openEuler:22.03-LTS","purl":"pkg:rpm/openEuler/unzip&distro=openEuler-22.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0-50.oe2203"}]}],"ecosystem_specific":{"aarch64":["unzip-help-6.0-50.oe2203.aarch64.rpm","unzip-6.0-50.oe2203.aarch64.rpm","unzip-debuginfo-6.0-50.oe2203.aarch64.rpm","unzip-debugsource-6.0-50.oe2203.aarch64.rpm"],"src":["unzip-6.0-50.oe2203.src.rpm"],"x86_64":["unzip-debuginfo-6.0-50.oe2203.x86_64.rpm","unzip-6.0-50.oe2203.x86_64.rpm","unzip-help-6.0-50.oe2203.x86_64.rpm","unzip-debugsource-6.0-50.oe2203.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2022-1902.json"}}],"schema_version":"1.7.5"}
