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."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/Mbed-TLS/mbedtls/releases"},{"url":"https://mbed-tls.readthedocs.io/en/latest/security-advisories/advisories/mbedtls-security-advisory-2022-07.html"},{"name":"[debian-lts-announce] 20221225 [SECURITY] [DLA 3249-1] mbedtls security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T09:36:44.078Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/Mbed-TLS/mbedtls/releases","tags":["x_transferred"]},{"url":"https://mbed-tls.readthedocs.io/en/latest/security-advisories/advisories/mbedtls-security-advisory-2022-07.html","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20221225 [SECURITY] [DLA 3249-1] mbedtls security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html"}]}]}}
