Sql injection

The getclientmasterkey function in s2srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, which allows man-in-the-middle attackers to...

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...

Scientific Linux Security Update : openssl on SL5.x i386/x86_64 (20160301) (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker can potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack is...
