How to Fix GHSA-crjg-w57m-rqqf

To remediate this vulnerability, upgrade all affected Dnsjava dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dnsjava:dnsjava fixed: 3.6.0 
<dependency>
    <groupId>dnsjava</groupId>
    <artifactId>dnsjava</artifactId>
    <version>3.6.0</version>
</dependency>
org.jitsi:dnssecjava fixed: Latest secure release 
<dependency>
    <groupId>org.jitsi</groupId>
    <artifactId>dnssecjava</artifactId>
    <version>Latest secure release</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=dnsjava

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-crjg-w57m-rqqf, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=dnsjava

Analyze the terminal output to locate any version of Dnsjava in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.6.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=dnsjava command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Dnsjava, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Users using the `ValidatingResolver` for DNSSEC validation can run into CPU exhaustion with specially crafted DNSSEC-signed zones. ### Patches Users should upgrade to dnsjava v3.6.0 ### Workarounds Although not recommended, only using a non-validating resolver, will remove the vulnerability. ### References https://www.athene-center.de/en/keytrap
