Fedora 28: FEDORA-2018-4f2c2615b3 Moderate: Apache POI Denial Of Service

The Apache POI Project's mission is to create and maintain Java APIs for

manipulating various file formats based upon the Office Open XML standards

(OOXML) and Microsoft's OLE 2 Compound Document format (OLE2). In short, you

can read and write MS Excel files using Java. In addition, you can read and

write MS Word and MS PowerPoint files using Java. Apache POI is your Java

Excel solution (for Excel 97-2008). We have a complete API for porting other

OOXML and OLE2 formats and welcome others to participate.

OLE2 files include most Microsoft Office files such as XLS, DOC, and PPT as

well as MFC serialization API based file formats. The project provides APIs

for the OLE2 Filesystem (POIFS) and OLE2 Document Properties (HPSF).

Office OpenXML Format is the new standards based XML file format found in

Microsoft Office 2007 and 2008. This includes XLSX, DOCX and PPTX. The

project provides a low level API to support the Open Packaging Conventions

using openxml4j.

For each MS Office application there exists a component module that attempts

to provide a common high level Java API to both OLE2 and OOXML document

formats. This is most developed for Excel workbooks (SS=HSSF+XSSF). Work is

progressing for Word documents (HWPF+XWPF) and PowerPoint presentations

(HSLF+XSLF).

The project has recently added support for Outlook (HSMF). Microsoft opened

the specifications to this format in October 2007. We would welcome

contributions.

There are also projects for Visio (HDGF) and Publisher (HPBF).
