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-jdk16.
Overview
org.bouncycastle:bcprov-jdk16 is a Bouncy Castle Crypto package that is a Java implementation of cryptographic algorithms. This jar contains JCE provider and lightweight API for the Bouncy Castle Cryptography APIs for JDK 1.6.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in PKCS12KeyStoreSpi, which feeds the attacker-controlled KDF iteration count from a PKCS#12 file's MAC data and encrypted bags into key derivation during engineLoad() without enforcing any upper bound. An attacker can pin a CPU core for an extended period and exhaust server resources by supplying a PKCS#12 keystore whose MAC or bag PBE parameters declare a very large iteration count, up to 2^31-1. This requires the application to load the attacker-supplied keystore, and the costly derivation runs during MAC verification and bag decryption regardless of whether the supplied password matches.
