Overview
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.
