Advisory Summary

CVE-2019-25563 is a MODERATE (CVSS 6.2) security vulnerability vulnerability (CWE-226: Sensitive Information in Resource Not Removed Before Reuse) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product releases a resource such as memory or a file so that it can be made available for reuse, but it does not clear or "zeroize" the information contained in the resource before the product performs a critical state transition or makes the resource available for reuse by other entities.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2019-25563

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

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

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-25563, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

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

Note: The mvn dependency:tree 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-226: Sensitive Information in Resource Not Removed Before Reuse, where the product releases a resource such as memory or a file so that it can be made available for reuse, but it does not clear or "zeroize" the information contained in the resource before the product performs a critical state transition or makes the resource available for reuse by other entities. In Software, 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

PCHelpWareV2 1.0.0.5 contains a denial of service vulnerability that allows local attackers to crash the application by supplying a malformed image file. Attackers can trigger the vulnerability through the Create SC feature by selecting a crafted BMP file with an oversized buffer, causing the application to crash.
