低危 OpenSSL 1.1.1d/1.1.1e/1.1.1f TLS 1.3 Handshake SSL_check_chain() Application 拒绝服务漏洞
CVE编号
CVE-2020-1967利用情况
POC 已公开补丁情况
官方补丁披露时间
2020-04-22漏洞描述
在TLS 1.3握手期间或之后调用SSL_check_chain()函数的服务器或客户端应用程序可能会崩溃，原因是对“signature_algorithms_cert”TLS扩展的错误处理导致NULL指针取消引用。如果从对等方接收到无效或无法识别的签名算法，则会发生崩溃。这可能被恶意的对等点在拒绝服务攻击中利用。OpenSSL版本1.1.1d、1.1.1e和1.1.1f都受到这个问题的影响。这个问题不影响1.1.1之前的OpenSSL版本。在OpenSSL 1.1.1g中修复(受1.1.1d-1.1.1f影响)。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接：https://www.openssl.org/news/secadv/20200421.txt受影响软件情况
