{"id":"ALPINE-CVE-2019-13377","details":"The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable to side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool curves are used. An attacker may be able to gain leaked information from a side-channel attack that can be used for full password recovery.","modified":"2026-09-09T06:17:50.069799868Z","published":"2019-08-15T17:15:13.410Z","upstream":["CVE-2019-13377"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-13377"}],"affected":[{"package":{"name":"hostapd","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/hostapd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0"},{"fixed":"2.8-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-13377.json"}},{"package":{"name":"hostapd","ecosystem":"Alpine:v3.9","purl":"pkg:apk/alpine/hostapd?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0"},{"fixed":"2.7-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-13377.json"}},{"package":{"name":"wpa_supplicant","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/wpa_supplicant?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-13377.json"}},{"package":{"name":"wpa_supplicant","ecosystem":"Alpine:v3.9","purl":"pkg:apk/alpine/wpa_supplicant?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-13377.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
