Hi,

The following vulnerability was published for bouncycastle.

CVE-2023-33202[0]:
| 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.
