Fixed in: LibreOffice 4.2.5
It was discovered during routine code review that LibreOffice >= 4.1.4/4.2.0 unconditionally executed certain VBA macros on loading Microsoft Office documents, contrary to user expectations.
Users are recommended to upgrade to 4.2.5.
Thanks to Stephen Bergmann of Red Hat, Inc. for discovering this flaw.
