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.
