Vulnerability Title
Netty: Out-of-date OCSP Responses Accepted by OcspServerCertificateValidator
Vulnerability Description
Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the OcspServerCertificateValidator flags an out-of-date OCSP response but does not stop processing it, so an expired GOOD response is still reported as VALID, letting an on-path attacker replay a stale GOOD response to bypass revocation of a since-revoked certificate. Exploitation can lead to certificate revocation bypass via replay of an expired OCSP response. Any application using OcspServerCertificateValidator is affected; a revoked certificate can be accepted. This issue has been fixed in versions 4.1.136.Final and 4.2.16.Final.

Vulnerability Title
Netty 加密问题漏洞
Vulnerability Description
Netty是Netty团队开源的一款非阻塞I/O客户端-服务器框架,它主要用于开发Java网络应用程序,如协议服务器和客户端等。 Netty 4.1.136.Final之前版本和4.2.0.Final至4.2.16.Final之前版本存在加密问题漏洞,该漏洞源于OcspServerCertificateValidator对过期的OCSP响应处理不当,导致攻击者可通过重放过期的OCSP响应绕过证书撤销,使得已吊销的证书仍可被接受。
