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 •
