{"id":"ALPINE-CVE-2022-35409","details":"An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server that causes a heap-based buffer over-read of up to 255 bytes. This can cause a server crash or possibly information disclosure based on error responses. Affected configurations have MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled and MBEDTLS_SSL_IN_CONTENT_LEN less than a threshold that depends on the configuration: 258 bytes if using mbedtls_ssl_cookie_check, and possibly up to 571 bytes with a custom cookie check function.","modified":"2026-03-09T01:21:53.416796Z","published":"2022-07-15T14:15:09.840Z","upstream":["CVE-2022-35409"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-35409"}],"affected":[{"package":{"name":"mbedtls","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/mbedtls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.1-r0"}]}],"versions":["2.0.0-r0","2.1.2-r0","2.11.0-r0","2.12.0-r0","2.14.1-r0","2.16.0-r0","2.16.1-r0","2.16.1-r1","2.16.10-r0","2.16.10-r1","2.16.12-r0","2.16.12-r1","2.16.2-r0","2.16.3-r0","2.16.5-r0","2.16.6-r0","2.16.8-r0","2.16.9-r0","2.2.0-r0","2.2.0-r1","2.2.1-r0","2.28.0-r0","2.3.0-r0","2.4.0-r0","2.4.1-r0","2.4.2-r0","2.5.1-r0","2.6.0-r0","2.6.1-r0","2.7.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-35409.json"}},{"package":{"name":"mbedtls","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/mbedtls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.1-r0"}]}],"versions":["2.0.0-r0","2.1.2-r0","2.11.0-r0","2.12.0-r0","2.14.1-r0","2.16.0-r0","2.16.1-r0","2.16.1-r1","2.16.10-r0","2.16.10-r1","2.16.12-r0","2.16.12-r1","2.16.2-r0","2.16.3-r0","2.16.5-r0","2.16.6-r0","2.16.8-r0","2.16.9-r0","2.2.0-r0","2.2.0-r1","2.2.1-r0","2.28.0-r0","2.3.0-r0","2.4.0-r0","2.4.1-r0","2.4.2-r0","2.5.1-r0","2.6.0-r0","2.6.1-r0","2.7.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-35409.json"}},{"package":{"name":"mbedtls","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/mbedtls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.1-r0"}]}],"versions":["2.0.0-r0","2.1.2-r0","2.11.0-r0","2.12.0-r0","2.14.1-r0","2.16.0-r0","2.16.1-r0","2.16.1-r1","2.16.10-r0","2.16.10-r1","2.16.12-r0","2.16.12-r1","2.16.2-r0","2.16.3-r0","2.16.5-r0","2.16.6-r0","2.16.8-r0","2.16.9-r0","2.2.0-r0","2.2.0-r1","2.2.1-r0","2.28.0-r0","2.3.0-r0","2.4.0-r0","2.4.1-r0","2.4.2-r0","2.5.1-r0","2.6.0-r0","2.6.1-r0","2.7.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-35409.json"}},{"package":{"name":"mbedtls","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/mbedtls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.1-r0"}]}],"versions":["2.0.0-r0","2.1.2-r0","2.11.0-r0","2.12.0-r0","2.14.1-r0","2.16.0-r0","2.16.1-r0","2.16.1-r1","2.16.10-r0","2.16.10-r1","2.16.12-r0","2.16.12-r1","2.16.2-r0","2.16.3-r0","2.16.5-r0","2.16.6-r0","2.16.8-r0","2.16.9-r0","2.2.0-r0","2.2.0-r1","2.2.1-r0","2.28.0-r0","2.3.0-r0","2.4.0-r0","2.4.1-r0","2.4.2-r0","2.5.1-r0","2.6.0-r0","2.6.1-r0","2.7.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-35409.json"}},{"package":{"name":"mbedtls","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/mbedtls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.1-r0"}]}],"versions":["2.0.0-r0","2.1.2-r0","2.11.0-r0","2.12.0-r0","2.14.1-r0","2.16.0-r0","2.16.1-r0","2.16.1-r1","2.16.10-r0","2.16.10-r1","2.16.12-r0","2.16.12-r1","2.16.2-r0","2.16.3-r0","2.16.5-r0","2.16.6-r0","2.16.8-r0","2.16.9-r0","2.2.0-r0","2.2.0-r1","2.2.1-r0","2.28.0-r0","2.3.0-r0","2.4.0-r0","2.4.1-r0","2.4.2-r0","2.5.1-r0","2.6.0-r0","2.6.1-r0","2.7.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-35409.json"}},{"package":{"name":"mbedtls","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/mbedtls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.1-r0"}]}],"versions":["2.0.0-r0","2.1.2-r0","2.11.0-r0","2.12.0-r0","2.14.1-r0","2.16.0-r0","2.16.1-r0","2.16.1-r1","2.16.10-r0","2.16.10-r1","2.16.12-r0","2.16.12-r1","2.16.2-r0","2.16.3-r0","2.16.5-r0","2.16.6-r0","2.16.8-r0","2.16.9-r0","2.2.0-r0","2.2.0-r1","2.2.1-r0","2.28.0-r0","2.3.0-r0","2.4.0-r0","2.4.1-r0","2.4.2-r0","2.5.1-r0","2.6.0-r0","2.6.1-r0","2.7.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-35409.json"}},{"package":{"name":"mbedtls","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/mbedtls?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.1-r0"}]}],"versions":["2.0.0-r0","2.1.2-r0","2.11.0-r0","2.12.0-r0","2.14.1-r0","2.16.0-r0","2.16.1-r0","2.16.1-r1","2.16.10-r0","2.16.10-r1","2.16.12-r0","2.16.12-r1","2.16.2-r0","2.16.3-r0","2.16.5-r0","2.16.6-r0","2.16.8-r0","2.16.9-r0","2.2.0-r0","2.2.0-r1","2.2.1-r0","2.28.0-r0","2.3.0-r0","2.4.0-r0","2.4.1-r0","2.4.2-r0","2.5.1-r0","2.6.0-r0","2.6.1-r0","2.7.0-r0"],"ecosystem_specific":{
