USN-706-1: Bind vulnerability

It was discovered that Bind did not properly perform signature verification. When DNSSEC with DSA signatures are in use, a remote attacker could exploit this to bypass signature validation to spoof DNS entries and poison DNS caches. Among other things, this could lead to misdirected email and web...

[oCERT-2008-016] Multiple OpenSSL signature verification API misuses

2008-016 multiple OpenSSL signature verification API misuse Description: Several functions inside the OpenSSL library incorrectly check the result after calling the EVPVerifyFinal function. This bug allows a malformed signature to be treated as a good signature rather than as an error. This issue...

OpenSSL 'EVP_VerifyFinal'函数签名验证漏洞

BUGTRAQ ID: 33150 CVE ID：CVE-2008-5077 CNCVE ID：CNCVE-20085077 OpenSSL是一款开放源码的SSL实现，用来实现网络通信的高强度加密。 部分OpenSSL函数验证DSA和ECDSA密钥时不正确验证"EVPVerifyFinal"函数返回值，发送特殊构建的签名证书链给客户端，可绕过签名检查。 通过恶意服务器或中间人攻击，可使证书链中的畸形SSL/TLS签名绕过客户端软件检查，导致盲目信任并泄漏敏感信息。 成功利用此漏洞需要服务器使用包含DSA或者ECDSA密钥的证书。 Ubuntu Ubuntu Linux 8.10 spar...
