Uncontrolled Resource Consumption

Bouncy Castle is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to insufficient bounds on PKCS12 MAC and bag-decryption KDF iteration counts, which allows an attacker to supply excessive iteration values and cause high computational resource consumption, resulting in...
