CVE-2024-39312

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.
