| <strong>Macro URL arbitrary script execution</strong> |
| </p> |
| <p style="text-align:center; font-size:larger"> |
| <strong>Fixed in Apache OpenOffice 4.1.15</strong> |
| </p> |
| <p> |
| <strong>Description</strong> |
| </p> |
| <p> |
| Apache OpenOffice documents can contain links that call internal macros with arbitrary |
| arguments. Several URI Schemes are defined for this purpose. Links can be activated by |
| clicks, or by automatic document events. The execution of such links must be subject to |
| user approval. In the affected versions of Apache OpenOffice, approval for certain links |
| is not requested; when activated, such links could therefore result in arbitrary script |
| execution. This is a corner case of |
