CVE-2025-64404: Apache OpenOffice: Remote documents loaded without prompt via background and bullet images

[Arrigo Marchiori <ardovm () apache org>]

Severity: moderate 

Affected versions:

- Apache OpenOffice through 4.1.15

Description:

Apache OpenOffice documents can contain links to other files. A missing Authorization vulnerability in Apache 
OpenOffice allowed an attacker to craft a document that would cause external links 
to be loaded without prompt. In the affected versions of Apache OpenOffice, documents that used background fill images, 
or bullet images, linked to external files would 
load the contents of those files without prompting the user for 
permission to do so.

This issue affects Apache OpenOffice: through 4.1.15.

Users are recommended to upgrade to version 4.1.16, which fixes the issue.
