Moderate: apache-commons-vfs security update (Amazon Linux 2)

Published Apr 23, 2025 · Updated Apr 30, 2025

Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2025-27553: Relative Path Traversal vulnerability in Apache Commons VFS before 2.10.0. The FileObject API in Commons VFS has a 'resolveFile' method that takes a 'scope' parameter. Specifying 'NameScope.DESCENDENT' promises that "an exception is thrown if the resolved file is not a descendent of the base file". However, when the path contains encoded ".." characters (for example, "%2E%2E/bar.txt"), it might return file objects that are not a descendent of the base file, without throwing an exception. This issue affects Apache Commons VFS: before 2.10.0. Users are recommended to upgrade to version 2.10.0, which fixes the issue.
