dtls-fuzzer

dtls-fuzzer 是一个Java工具，用于对DTLS服务器执行协议状态模糊测试。具体而言，它支持以下功能： 1. 给定一个字母表，它可以自动生成本地DTLS服务器实现的模型； 2. 给定一个测试（输入序列）和一个字母表，它可以在DTLS服务器实现上执行该测试； 3. 它可以运行批量学习任务，涉及多次学习运行。 dtls-fuzzer 使用 TLS-Attacker 来生成/解析DTLS消息以及维护状态。 为此，TLS-Attacker 已扩展了对DTLS的支持。 dtls-fuzzer 依赖于 版本 3.0b 的 TLS-Attacker ，该版本实现了DTLS增强功能。 制品内容...

CVE-2021-42146

An issue was discovered in Contiki-NG tinyDTLS through master branch 53a0d97. DTLS servers allow remote attackers to reuse the same epoch number within two times the TCP maximum segment lifetime, which is prohibited in RFC6347. This vulnerability allows remote attackers to obtain sensitive...

Updated mbedtls packages fix security vulnerability

An unauthenticated remote host could send an invalid ClientHello message in which the declared length of the cookie extends past the end of the message. A DTLS server with MBEDTLSSSLDTLSCLIENTPORTREUSE enabled would read past the end of the message up to the declared length of the cookie. This...

lib32-openssl: man-in-the-middle

During certificate verification, OpenSSL will attempt to find an alternative certificate chain if the first attempt to build such a chain fails. An error in the implementation of this logic can mean that an attacker could cause certain checks on untrusted certificates to be bypassed, such as the ...
