How to Fix CVE-2019-16555

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

com.sonyericsson.jenkins.plugins.bfa:build-failure-analyzer fixed: 1.24.2 
<dependency>
    <groupId>com.sonyericsson.jenkins.plugins.bfa</groupId>
    <artifactId>build-failure-analyzer</artifactId>
    <version>1.24.2</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=com.sonyericsson.jenkins.plugins.bfa

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-16555, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.sonyericsson.jenkins.plugins.bfa

Analyze the terminal output to locate any version of Build failure analyzer in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.24.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.sonyericsson.jenkins.plugins.bfa 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 Build failure analyzer, 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

A user-supplied regular expression in Jenkins Build Failure Analyzer Plugin 1.24.1 and earlier was processed in a way that wasn't interruptible, allowing attackers to have Jenkins evaluate a regular expression without the ability to interrupt this process.
