CVE-2023-33202

Summary

CVE-2023-33202 is a newly disclosed vulnerability affecting Bouncy Castle for Java before version 1.73. This issue involves the org.bouncycastle.openssl.PEMParser class, which is used to parse OpenSSL PEM encoded streams containing X.509 certificates, PKCS8 keys, and PKCS7 objects. The vulnerability permits an attacker to craft ASN.1 data that, when processed by the PEMParser, results in an OutOfMemoryError. Consequently, a Denial of Service (DoS) attack can be launched against systems utilizing this vulnerable component. Importantly, for users of the FIPS Java API, BC-FJA 1.0.2.3 and earlier versions are susceptible, while BC-FJA 1.0.2.4 has been patched to address this issue.
