Uncontrolled Recursion Affecting org.bouncycastle:bcprov-debug-jdk15on package, versions [1.70,]
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.

There is no fixed version for org.bouncycastle:bcprov-debug-jdk15on.
Overview
org.bouncycastle:bcprov-debug-jdk15on is a Java implementation of cryptographic algorithms.
Affected versions of this package are vulnerable to Uncontrolled Recursion in the OERInputStream.parse(Element) method, which processes the SEQ, CHOICE, and Supplier children of an IEEE 1609.2 structure recursively without enforcing a depth limit. An attacker can crash the parsing thread or the JVM with a StackOverflowError by supplying a roughly 2 to 4 KB IEEE 1609.2 message containing hundreds of nested signedData payloads to the ETSISignedData(byte[]) or ETSIEncryptedData(byte[]) entry points, which parse untrusted input before signature verification. Exploitation reaches the recursion pre-verification because the schema's self-referential mayRecurse cycle (Ieee1609Dot2Data back to itself) is only validated in test tooling, not at runtime, so it requires only that the application pass untrusted IEEE 1609.2 data to those entry points.
