Vulnerability Title
Botan has a Denial of Service Due to Excessive Name Constraints
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. Prior to 3.5.0 and 2.19.5, checking name constraints in X.509 certificates is quadratic in the number of names and name constraints. An attacker who presented a certificate chain which contained a very large number of names in the SubjectAlternativeName, signed by a CA certificate which contained a large number of name constraints, could cause a denial of service. The problem has been addressed in Botan 3.5.0 and a partial backport has also been applied and is included in Botan 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 3.5.0和2.19.5之前版本存在安全漏洞，该漏洞源于检查X.509证书中的名称约束与名称和名称约束的数量成二次方关系，攻击者可能导致拒绝服务。
