bcprov-jdk18onTL;DR
Loading a BCFKS keystore honours KDF iteration/cost parameters taken from the keystore file without an upper bound. A crafted BCFKS file can demand extreme KDF work during load. Applications that open untrusted BCFKS keystores can be stalled or exhausted. The fix caps accepted KDF cost parameters when loading BCFKS files.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you load BCFKS keystores from untrusted files.
Background info
