How to Fix CVE-2012-5370

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

org.jruby:jruby-parent fixed: 1.7.1 
<dependency>
    <groupId>org.jruby</groupId>
    <artifactId>jruby-parent</artifactId>
    <version>1.7.1</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=org.jruby

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2012-5370, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jruby

Analyze the terminal output to locate any version of Jruby parent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.7.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jruby 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Jruby parent, 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

JRuby computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4838.
