bcpkix-jdk14 is vulnerable to Uncontrolled Resource Consumption
69
Medium Risk
This Affects:
bcpkix-jdk14TL;DR
Password-based cryptography entry points accept attacker-controlled KDF cost parameters without complete bounds, so parsing untrusted password-encrypted PKCS#12, PBMAC1, or related PBE data spends excessive CPU or memory before authentication succeeds. The fix bounds iteration counts, key length and the remaining PBMAC1 parameters before derivation or allocation.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you parse untrusted password-encrypted PKCS#8, PKCS#12, PBMAC1, or related PBE data with the PKIX APIs.
Background info
bcpkix-jdk14 is vulnerable to Uncontrolled Resource Consumption in versions 1.71 - 1.85.
How to fix this
Upgrade the bcpkix-jdk14 library to the patch version.
