         Description
       </strong>
     </p>
     <p>
       OpenOffice documents can contain macros. The execution of those macros is controlled by the document security settings,
       typically execution of macros are blocked by default. A URL decoding flaw existed in how the URLs to the macros within
       the document were processed and categorized, resulting in the possibility to construct a document where macro execution
       bypassed the security settings. The documents were correctly detected as containing macros, and prompted the user to
       their existence within the documents, but macros within the document were subsequently not controlled by the security
       settings allowing arbitrary macro execution.
       This issue affects: OpenOffice 4.1.6 and older versions.
