Title: Botan de Randombit, Description: Botan es una biblioteca de criptografía C++. Antes de la versión 3.11.1, la implementación de TLS 1.3 permitía que los registros ApplicationData fueran procesados antes de que se recibiera el mensaje Finished. Un servidor que intenta aplicar la autenticación del cliente mediante certificados puede ser eludido por un cliente que omite por completo los mensajes Certificate, CertificateVerify y Finished y en su lugar envía registros de datos de aplicación. Esta vulnerabilidad está corregida en la versión 3.11.1.

Botan is a C++ cryptography library. Prior to version 3.11.1, the TLS 1.3 implementation allowed ApplicationData records to be processed prior to the Finished message being received. A server which is attempting to enforce client authentication via certificates can by bypassed by a client which entirely omits Certificate, CertificateVerify, and the Finished message and instead sends application data records. This vulnerability is fixed in 3.11.1.
