Advisory Summary

CVE-2025-26305 is a HIGH (CVSS 8.2) security vulnerability vulnerability (CWE-244: Improper Clearing of Heap Memory Before Release ('Heap Inspection')) affecting Software libraries in the Maven ecosystem. The weakness occurs when using realloc() to resize buffers that store sensitive information can leave the sensitive information exposed to attack, because it is not removed from memory.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2025-26305

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-2025-26305, 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-244: Improper Clearing of Heap Memory Before Release ('Heap Inspection'), where using realloc() to resize buffers that store sensitive information can leave the sensitive information exposed to attack, because it is not removed from memory. 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

A memory leak has been identified in the parseSWF_SOUNDINFO function in util/parser.c of libming v0.4.8, which allows attackers to cause a denial of service via a crafted SWF file.
