CVE-2022-2576

In Eclipse Californium version 2.0.0 to 2.7.2 and 3.0.0-3.5.0 a DTLS resumption handshake falls back to a DTLS full handshake on a parameter mismatch without using a HelloVerifyRequest. Especially, if used with certificate based cipher suites, that results in message amplification DDoS other peer...

CVE-2022-2576

In Eclipse Californium, CVE-2022-2576 affects versions 2.0.0–2.7.2 and 3.0.0–3.5.0. The DTLS resumption handshake can fall back to a full DTLS handshake on parameter mismatch without a HelloVerifyRequest, which, when used with certificate-based cipher suites, enables message amplification that ca...

Denial Of Service (DoS)

mbedtls is vulnerable to denial of service. The vulnerability exists through a buffer overread when the dtls server with MBEDTLSSSLDTLSCLIENTPORTREUSE in use receives a ClientHello message with a cookie whose declared length exceeds the end of the allocated buffer which allows an attacker to caus...

CVE-2022-35409

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...

Mbed TLS 缓冲区错误漏洞

Mbed TLS is an open source, portable, easy-to-use, readable and flexible SSL library. A buffer error vulnerability exists in Mbed TLS versions prior to 2.28.2 and 3.x versions prior to 3.2.0, which stems from the fact that in certain configurations, an unauthenticated attacker can send an invalid...
