Bouncy Castle BC Java before 1.66, BC C# .NET before 1.8.7, BC-FJA before 1.0.1.2, 1.0.2.1, and BC-FNA before 1.0.1.1 have a timing issue within the EC math library that can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures. Bouncy Castle BC Java versiones anteriores a 1.66, BC C # .NET versiones anteriores a 1.8.7, BC-FJA versiones anteriores a 1.0.1.2, 1.0.2.1 y BC-FNA versiones anteriores a 1.0.1.1, presentan un problema de sincronización dentro de la biblioteca EC math que puede exponer información sobre la clave privada cuando un atacante es capaz de observar información de sincronización para la generación de múltiples firmas ECDSA deterministas A flaw was found in bouncycastle.

An issue was discovered in Legion of the Bouncy Castle BC Java 1.65 and 1.66. The OpenBSDBCrypt.checkPassword utility method compared incorrect data when checking the password, allowing incorrect passwords to indicate they were matching with previously hashed ones that were different. Se detectó un problema en Legion of the Bouncy Castle BC Java versiones 1.65 y 1.66. El método de la utilidad OpenBSDBCrypt.checkPassword comparó datos incorrectos al comprobar la contraseña, permitiendo a unas contraseñas incorrectas indicar que coinciden con otras previamente en hash que eran diferentes A flaw was found in bouncycastle.

In Legion of the Bouncy Castle BC before 1.61 and BC-FJA before 1.0.1.2, attackers can obtain sensitive information about a private exponent because of Observable Differences in Behavior to Error Inputs. This occurs in org.bouncycastle.crypto.encodings.OAEPEncoding. Sending invalid ciphertext that decrypts to a short payload in the OAEP Decoder could result in the throwing of an early exception, potentially leaking some information about the private exponent of the RSA private key performing the encryption. En Legion of the Bouncy Castle BC versiones anteriores a 1.61 y BC-FJA versiones anteriores a 1.0.1.2, los atacantes pueden obtener información confidencial sobre un exponente privado debido a las diferencias observables en el comportamiento de las entradas de error. Esto se presenta en org.bouncycastle.crypto.encodings.OAEPEncoding. • https://github.com/bcgit/bc-java/wiki/CVE-2020-26939 https://lists.apache.org/thread.html/r8c36ba34e80e05eecb1f80071cc834d705616f315b634ec0c7d8f42e%40%3Cissues.solr.apache.org%3E • CWE-203: Observable Discrepancy •

The ASN.1 parser in Bouncy Castle Crypto (aka BC Java) 1.63 can trigger a large attempted memory allocation, and resultant OutOfMemoryError error, via crafted ASN.1 data. This is fixed in 1.64. El analizador ASN.1 en Bouncy Castle Crypto (también se conoce como BC Java) versión 1.63, puede desencadenar un intento de asignación de memoria grande y un error OutOfMemoryError resultante, por medio de datos ASN.1 diseñados. Esto se corrige en la versión 1.64. • https://lists.apache.org/thread.html/r02f887807a49cfd1f1ad53f7a61f3f8e12f60ba2c930bec163031209%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r16c3a90cb35ae8a9c74fd5c813c16d6ac255709c9f9d71cd409e007d%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r467ade3fef3493f1fff1a68a256d087874e1f858ad1de7a49fe05d27%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r4d475dcaf4f57115fa57d8e06c3823ca398b35468429e7946ebaefdc%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r79b6a6aa0dd1aeb57bd253d94794bc96f1ec005953c4bd5414cc0db0&# • CWE-770: Allocation of Resources Without Limits or Throttling •
