{"id":"ALPINE-CVE-2020-11501","details":"GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol.","modified":"2026-09-11T10:17:51.364972554Z","published":"2020-04-03T13:15:13.170Z","upstream":["CVE-2020-11501"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-11501"}],"affected":[{"package":{"name":"gnutls","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.8-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"fixed":"3.6.13-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-11501.json"}},{"package":{"name":"gnutls","ecosystem":"Alpine:v3.8","purl":"pkg:apk/alpine/gnutls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.3"},{"
