OpenSSL 1.0.2 < 1.0.2g Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.2g. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2g advisory. - The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a...

CVE-2016-0703

CVE-2016-0703 concerns OpenSSL SSLv2: the get_client_master_key function in s2_srvr.c accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH for arbitrary ciphers, enabling Bleichenbacher-style padding oracle exploitation to recover the MASTER-KEY and decrypt TLS traffic. Public sources attribute t...

Cross-protocol attack on TLS using SSLv2 (DROWN) (CVE-2016-0800)

现在流行的服务器和客户端使用TLS加密, 然而由于错误配置, 许多服务器仍然支持SSLv2, 这是一种古老的协议, 许多客户端已经不支持 SSLv2。 DROWN攻击可以威胁到还在支持 SSLv2 的服务端和客户端,允许攻击者通过发送 probe 到支持 SSLv2 的使用相同密钥的服务端和客户端解密 TLS 通信。 官方关于漏洞的公告: A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and...

ownCloud: DROWN Attack

Hi, I want to report a drown attack in .owncloud.com. A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. Note that traffic between clients and non-vulnerable serve...

openssl: SSLv2 Bleichenbacher protection overwrites wrong bytes for export ciphers

It was discovered that the SSLv2 protocol implementation in OpenSSL did not properly implement the Bleichenbacher protection for export cipher suites. An attacker could use a SSLv2 server using OpenSSL as a Bleichenbacher oracle...
