{"id":"ALPINE-CVE-2020-13645","details":"In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification. Applications that fail to provide the server identity, including Balsa before 2.5.11 and 2.6.x before 2.6.1, accept a TLS certificate if the certificate is valid for any host.","modified":"2026-11-03T06:32:23.721724330Z","published":"2020-05-28T12:15:11.173Z","upstream":["CVE-2020-13645"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-13645"}],"affected":[{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}},{"package":{"name":"glib-networking","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/glib-networking?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.64.0"},{"fixed":"2.64.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-13645.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
