LibreOffice is an open source, community-developed office productivity suite. It includes the key desktop applications, such as a word processor, spreadsheet application, presentation manager, formula editor, and a drawing program. Multiple heap-based buffer overflow flaws were found in the way LibreOffice processed encryption information in the manifest files of OpenDocument Format files. An attacker could provide a specially-crafted OpenDocument Format file that, when opened in a LibreOffice application, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
