{"id":"ALPINE-CVE-2021-20271","details":"A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is to data integrity, confidentiality, and system availability.","modified":"2026-11-03T06:32:26.883104825Z","published":"2021-03-26T17:15:13Z","upstream":["CVE-2021-20271"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-20271"}],"affected":[{"package":{"name":"rpm","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}},{"package":{"name":"rpm","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/rpm?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.16.1.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-20271.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
