CVE-2023-33202 – bc-java: Out of memory while parsing ASN.1 crafted data in org.bouncycastle.openssl.PEMParser class
https://notcve.org/view.php?id=CVE-2023-33202
Bouncy Castle for Java before 1.73 contains a potential Denial of Service (DoS) issue within the Bouncy Castle org.bouncycastle.openssl.PEMParser class. This class parses OpenSSL PEM encoded streams containing X.509 certificates, PKCS8 encoded keys, and PKCS7 objects. Parsing a file that has crafted ASN.1 data through the PEMParser causes an OutOfMemoryError, which can enable a denial of service attack. (For users of the FIPS Java API: BC-FJA 1.0.2.3 and earlier are affected; BC-FJA 1.0.2.4 is fixed.) Bouncy Castle para Java anterior a 1.73 contiene un posible problema de denegación de servicio (DoS) dentro de la clase Bouncy Castle org.bouncycastle.openssl.PEMParser. • https://bouncycastle.org https://github.com/bcgit/bc-java/wiki/CVE-2023-33202 https://security.netapp.com/advisory/ntap-20240125-0001 https://access.redhat.com/security/cve/CVE-2023-33202 https://bugzilla.redhat.com/show_bug.cgi?id=2251281 • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-15522 – bouncycastle: Timing issue within the EC math library
https://notcve.org/view.php?id=CVE-2020-15522
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. A timing issue within the EC math library can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures. • https://github.com/bcgit/bc-csharp/wiki/CVE-2020-15522 https://github.com/bcgit/bc-java/wiki/CVE-2020-15522 https://security.netapp.com/advisory/ntap-20210622-0007 https://www.bouncycastle.org/releasenotes.html https://access.redhat.com/security/cve/CVE-2020-15522 https://bugzilla.redhat.com/show_bug.cgi?id=1962879 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

Legion of the Bouncy Castle Legion of the Bouncy Castle Java Cryptography APIs 1.58 up to but not including 1.60 contains a CWE-470: Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in XMSS/XMSS^MT private key deserialization that can result in Deserializing an XMSS/XMSS^MT private key can result in the execution of unexpected code. This attack appear to be exploitable via A handcrafted private key can include references to unexpected classes which will be picked up from the class path for the executing application. This vulnerability appears to have been fixed in 1.60 and later. Las API Legion of the Bouncy Castle Java Cryptography de Legion of the Bouncy Castle en versiones hasta 1.58 pero sin incluir la versión 1.60, contiene una debilidad CWE-470: Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection'), vulnerabilidad en la deserialización de la clave privada XMSS/XMSS^MT que puede resultar en desrealizar una clave privada XMSS/XMSS^MT puede resultar en la ejecución de código inesperado.
