How to Fix CVE-2021-41561

To remediate this vulnerability, upgrade all affected Parquet 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.apache.parquet:parquet fixed: 1.12.2 
<dependency>
    <groupId>org.apache.parquet</groupId>
    <artifactId>parquet</artifactId>
    <version>1.12.2</version>
</dependency>
org.apache.parquet:parquet fixed: 1.11.2 
<dependency>
    <groupId>org.apache.parquet</groupId>
    <artifactId>parquet</artifactId>
    <version>1.11.2</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=org.apache.parquet

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-41561, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.parquet

Analyze the terminal output to locate any version of Parquet in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.12.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.parquet 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Parquet, 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

Improper Input Validation vulnerability in Parquet-MR of Apache Parquet allows an attacker to DoS by malicious Parquet files. This issue affects Apache Parquet-MR version 1.9.0 and later versions.
