NVD Description
Note: Versions mentioned in the description apply only to the upstream botan package and not the botan package as distributed by Debian.
Botan is a C++ cryptography library. From version 3.0.0 to before version 3.11.0, during X509 path validation, OCSP responses were checked for an appropriate status code, but critically omitted verifying the signature of the OCSP response itself. This issue has been patched in version 3.11.0.
