Vulnerability Title
Validation of SignedInfo
Vulnerability Description
xml-security is a library that implements XML signatures and encryption. Validation of an XML signature requires verification that the hash value of the related XML-document matches a specific DigestValue-value, but also that the cryptographic signature on the SignedInfo-tree (the one that contains the DigestValue) verifies and matches a trusted public key. If an attacker somehow (i.e. by exploiting a bug in PHP's canonicalization function) manages to manipulate the canonicalized version's DigestValue, it would be possible to forge the signature. This issue has been patched in version 1.6.12 and 5.0.0-alpha.13.

xml-security 数据伪造问题漏洞
Vulnerability Description
xml-security是SimpleSAMLphp开源的一个库。 xml-security 1.6.11版本、saml2 5.0.0-alpha.13版本存在数据伪造问题漏洞，该漏洞源于XML 签名验证需要验证相关 XML 文档的哈希值是否与特定的 DigestValue 值匹配，而且还需要验证 SignedInfo 树上的加密签名并匹配受信任的公钥， 攻击者利用该漏洞可以以某种方式操纵规范化版本的 DigestValue，并可能伪造签名。
