Uncontrolled Recursion Affecting org.bouncycastle:bcprov-debug-jdk14 package, versions [,1.85)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion in the force() method of LazyEncodedSequence, which parses the deferred SEQUENCE with a fresh ASN1InputStream whose nesting-depth counter is reset rather than inherited from the parent parse, and never calls createSubStream() or decrementDepth(). An attacker can crash the handling thread with a StackOverflowError by supplying a 40-50 KB DER-encoded CRL whose revokedCertificates field nests roughly 10,000 SEQUENCE structures. This requires the application to parse the CRL through X509CRLHolder or the BC CertificateFactory path, where revokedCertificates is held as an unevaluated lazy sequence until forced.
