Vulnerability Title
Botan has an Authorization Error due to Name Constraint Decoding Bug
Vulnerability Description
Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. A bug in the parsing of name constraint extensions in X.509 certificates meant that if the extension included both permitted subtrees and excluded subtrees, only the permitted subtree would be checked. If a certificate included a name which was permitted by the permitted subtree but also excluded by excluded subtree, it would be accepted. Fixed in versions 3.5.0 and 2.19.5.

Vulnerability Title
Botan 安全漏洞
Vulnerability Description
Botan是一款使用C++编写的加密算法库。该产品支持AES、DES、SHA-1、RSA、DSA和Diffie-Hellman等多种算法。 Botan存在安全漏洞，该漏洞源于X.509证书中的名称约束扩展解析中存在一个错误，这意味着如果扩展同时包含“permitted subtrees”和“excluded subtrees”，则只会检查“permitted subtrees”。
