bcprov-jdk18on is vulnerable to Inefficient Algorithmic Complexity
87
High Risk
This Affects:
bcprov-jdk18onTL;DR
Stringifying X.500 distinguished names performs escaping in quadratic time relative to input size. A large or highly escape-heavy DN can consume excessive CPU when converted to a string. Services that render or log untrusted DNs can be stalled. The fix uses linear-time escaping for DN stringification.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you convert untrusted X.500 DNs to strings.
Background info
bcprov-jdk18on is vulnerable to Inefficient Algorithmic Complexity in versions 0.0.1 - 1.84.0.
How to fix this
Upgrade the org.bouncycastle provider library for your JDK target (bcprov-jdk18on, bcprov-jdk15to18 or bcprov-jdk14) to the patch version.
