Macro URL arbitrary script execution without warning
Fixed in Apache OpenOffice 4.1.14
Description
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 OpenOffice, approval for certain links is not requested; when activated, such links could therefore result in arbitrary script execution.
