2014年4月7日,OpenSSL发布安全公告,在OpenSSL1.0.1版本至OpenSSL1.0.1f Beta1版本中存在漏洞,该漏洞中文名称为心脏滴血,英文名称为HeartBleed。其中Heart是指该漏洞位于心跳协议上,Bleed是因为该漏洞会造成数据泄露。即HeartBleed是在心跳协议上的一个数据泄露漏洞,OpenSSL库中用到了该心跳协议。HeartBleed主要存在与OpenSSL的1.0.1版本到1.0.1f版本。
Heartbleed 漏洞允许 Internet 上的任何人读取受 OpenSSL 软件易受攻击版本保护的系统内存。这损害了用于识别服务提供商和加密流量、用户名和密码以及实际内容的密钥。这允许攻击者窃听通信,直接从服务和用户窃取数据,并冒充服务和用户。SSL/TLS 为 Web、电子邮件、即时消息 (IM) 和一些虚拟专用网络 (VPN) 等应用程序提供 Internet 上的通信安全和隐私。
