30 Jan 2017 — In Botan 1.8.0 through 1.11.33, when decoding BER data an integer overflow could occur, which would cause an incorrect length field to be computed. Some API callers may use the returned (incorrect and attacker controlled) length field in a way which later causes memory corruption or other failure. En Botan 1.8.0 hasta la versión 1.11.33, al decodificar datos BER podría producirse un desbordamiento de enteros, lo que causaría que se calculara un campo de longitud incorrecto. Algunos llamadores API pueden uti... • http://www.securityfocus.com/bid/95879 • CWE-190: Integer Overflow or Wraparound •

13 May 2016 — Botan 1.11.x before 1.11.29 does not enforce TLS policy for (1) signature algorithms and (2) ECC curves, which allows remote attackers to conduct downgrade attacks via unspecified vectors. Botan 1.11.x en versiones anteriores a 1.11.29 no hace cumplir la política TLS para (1) algoritmos de firma y (2) curvas ECC, lo que permite a atacantes remotos llevar a cabo ataques de degradación a través de vectores no especificados. Multiple vulnerabilities have been found in Botan, the worst of which might allow remo... • http://botan.randombit.net/security.html • CWE-20: Improper Input Validation •

02 May 2016 — Botan before 1.10.13 and 1.11.x before 1.11.29 do not use a constant-time algorithm to perform a modular inverse on the signature nonce k, which might allow remote attackers to obtain ECDSA secret keys via a timing side-channel attack. Botan en versiones anteriores a 1.10.13 y 1.11.x en versiones anteriores a 1.11.29 no utiliza un algoritmo de tiempo constante para realizar un inverso modular en la firma k nonce, lo que podría permitir a atacantes remotos obtener claves secretas ECDSA a través de un ataque ... • http://botan.randombit.net/security.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
