{"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":"2026-03-09T01:18:48.489053Z","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":"0"},{"fixed":"2.8-r1"}]}],"versions":["0.6.10-r0","0.6.10-r1","0.6.10-r2","0.6.9-r0","0.6.9-r1","0.7.3-r0","0.7.3-r1","0.7.3-r2","1.0-r0","1.0-r1","1.0-r2","1.1-r0","2.0-r0","2.0-r1","2.1-r0","2.2-r0","2.3-r0","2.4-r0","2.4-r1","2.5-r0","2.5-r1","2.5-r2","2.5-r3","2.6-r0","2.6-r1","2.6-r2","2.6-r3","2.6-r4","2.6-r5","2.7-r0","2.8-r0"],"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":"0"},{"fixed":"2.7-r4"}]}],"versions":["0.6.10-r0","0.6.10-r1","0.6.10-r2","0.6.9-r0","0.6.9-r1","0.7.3-r0","0.7.3-r1","0.7.3-r2","1.0-r0","1.0-r1","1.0-r2","1.1-r0","2.0-r0","2.0-r1","2.1-r0","2.2-r0","2.3-r0","2.4-r0","2.4-r1","2.5-r0","2.5-r1","2.5-r2","2.5-r3","2.6-r0","2.6-r1","2.6-r2","2.6-r3","2.6-r4","2.6-r5","2.7-r0","2.7-r1","2.7-r2","2.7-r3"],"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"}]}],"versions":["0.5.11-r0","0.6.10-r0","0.6.9-r0","0.6.9-r1","0.7.1-r0","0.7.1-r1","0.7.1-r2","0.7.2-r0","0.7.2-r1","0.7.2-r2","0.7.3-r0","0.7.3-r1","0.7.3-r2","1.0-r0","1.0-r1","1.0-r2","1.1-r0","1.1-r1","2.0-r0","2.0-r1","2.0-r2","2.0-r3","2.1-r0","2.1-r1","2.1-r2","2.2-r0","2.3-r0","2.3-r1","2.4-r0","2.4-r1","2.4-r2","2.4-r3","2.4-r4","2.4-r5","2.4-r6","2.4-r7","2.4-r8","2.5-r0","2.5-r1","2.5-r2","2.5-r3","2.6-r0","2.6-r1","2.6-r10","2.6-r11","2.6-r12","2.6-r13","2.6-r14","2.6-r15","2.6-r2","2.6-r3","2.6-r4","2.6-r5","2.6-r6","2.6-r7","2.6-r8","2.6-r9","2.7-r0","2.7-r1","2.7-r2","2.7-r3","2.8-r0","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":"wpa_supplicant","ecosystem":"Alpine:v3.9","purl":"pkg:apk/alpine/wpa_supplicant?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7-r4"}]}],"versions":["0.5.11-r0","0.6.10-r0","0.6.9-r0","0.6.9-r1","0.7.1-r0","0.7.1-r1","0.7.1-r2","0.7.2-r0","0.7.2-r1","0.7.2-r2","0.7.3-r0","0.7.3-r1","0.7.3-r2","1.0-r0","1.0-r1","1.0-r2","1.1-r0","1.1-r1","2.0-r0","2.0-r1","2.0-r2","2.0-r3","2.1-r0","2.1-r1","2.1-r2","2.2-r0","2.3-r0","2.3-r1","2.4-r0","2.4-r1","2.4-r2","2.4-r3","2.4-r4","2.4-r5","2.4-r6","2.4-r7","2.4-r8","2.5-r0","2.5-r1","2.5-r2","2.5-r3","2.6-r0","2.6-r1","2.6-r10","2.6-r11","2.6-r12","2.6-r13","2.6-r14","2.6-r15","2.6-r2","2.6-r3","2.6-r4","2.6-r5","2.6-r6","2.6-r7","2.6-r8","2.6-r9","2.7-r0","2.7-r1","2.7-r2","2.7-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-13377.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
