Aliases: CVE-2023-33202 GHSA-wjxj-5m7g-mg7q |
Bouncy Castle Denial of Service (DoS) 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. |

Bouncy Castle For Java LDAP injection vulnerability Bouncy Castle provides the `X509LDAPCertStoreSpi.java` class which can be used in conjunction with the CertPath API for validating certificate paths. Pre-1.73 the implementation did not check the X.500 name of any certificate, subject, or issuer being passed in for LDAP wild cards, meaning the presence of a wild car may lead to Information Disclosure. A potential attack would be to generate a self-signed certificate with a subject name that contains special characters, e.g: `CN=Subject*)(objectclass=`. This will be included into the filter and provides the attacker ability to specify additional attributes in the search query. This can be exploited as a blind LDAP injection: an attacker can enumerate valid attribute values using the boolean blind injection technique. The exploitation depends on the structure of the target LDAP directory, as well as what kind of errors are exposed to the user. Changes to the `X509LDAPCertStoreSpi.java` class add the additional checking of any X.500 name used to correctly escape wild card characters. | There are no reported fixed by versions. |

Logic error in Legion of the Bouncy Castle BC Java 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. |

| VCID-cuv2-m4kt-hqba | Timing based private key exposure in Bouncy Castle Bouncy Castle BC Java before 1.66, BC C# .NET before 1.8.7, BC-FJA before 1.0.2.1, BC before 1.66, 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. |
