Memory Allocation with Excessive Size Value Affecting org.bouncycastle:bcprov-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.

Upgrade org.bouncycastle:bcprov-jdk14 to version 1.85 or higher.
Overview
org.bouncycastle:bcprov-jdk14 is a Java implementation of cryptographic algorithms.
Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in HSSPublicKeyParameters.getInstance() and HSSSignature.getInstance(), which read the HSS level count L from an encoded public key without the RFC 8554 depth cap of 8 (enforced only during key generation) and then allocate arrays sized from that attacker-controlled value. An attacker can force an allocation of roughly 17 GB, driving the verifier to OutOfMemoryError, by supplying an HSS public key and signature that declare an oversized level count. This requires the verifier to process attacker-supplied HSS/LMS public keys and signatures, reachable via SubjectPublicKeyInfo, the JCA LMSKeyFactorySpi/LMSSignatureSpi, or CMS (RFC 9708) verification.
