There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache
    PDFBox Examples. This issue affects the ExtractEmbeddedFiles example in Apache PDFBox: from 2.0.24 through
    2.0.36, from 3.0.0 through 3.0.7. Users are recommended to update to version 2.0.37 or 3.0.8 once
    available. Until then, they should apply the fix provided in GitHub PR 427. The ExtractEmbeddedFiles
    example contained a path traversal vulnerability (CWE-22) mentioned in CVE-2026-23907. However the change
    in the releases 2.0.36 and 3.0.7 is flawed because it doesn't consider the file path separator. Because of
    that, a user having writing rights on /home/ABC could be victim to a malicious PDF resulting in a write
    attempt to any path starting with /home/ABC, e.g. "/home/ABCDEF". Users who have copied this example into
    their production code should apply the mentioned change. The example has been changed accordingly and is
    available in the project repository. (CVE-2026-33929)

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20923-1 advisory.

    Update to version 2.0.36.

    Security issues fixed:
