CVE-2026-44378

Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which prohibits indefinite length encodings. This vulnerability is fixed in 3.12.0.

Summary		(es) Botan es una biblioteca de criptografía C++. Antes de la versión 3.12.0, ciertos patrones de codificaciones de longitud indefinida en datos BER podrían causar un comportamiento cuadrático en el analizador, resultando en una denegación de servicio. Dichas codificaciones BER eran aceptadas incluso en estructuras que deben ser codificadas como DER, lo que prohíbe las codificaciones de longitud indefinida. Esta vulnerabilidad está corregida en la versión 3.12.0.
