CVE-2023-33202 PUBLISHED CVSS 5.5 MEDIUM

Bouncy Castle Denial of Service (DoS)

Reported by mitre · Published November 23, 2023

bcprov-jdk16 is fixed in 1.73 (Maven Central)

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.)
