T-003: Vulnerabilities in Microsoft Excel
Several remote code execution vulnerabilities exist in the way Microsoft Excel: 1) processes a VBA Performance Cache; 2) an improper memory allocationwhenloading Excel objects; and 3) a formula parsing vulnerability when parsing Microsoft Excel documents containing a specially crafted formula embedded inside a cell. The risk is MEDIUM. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Excel::Writer::XLSX::Package::Packager(3pm)		User Contributed Perl Documentation	       Excel::Writer::XLSX::Package::Packager(3pm)

NAME

       Packager - A class for creating the Excel XLSX package.

SYNOPSIS

       See the documentation for Excel::Writer::XLSX.

DESCRIPTION

       This module is used in conjunction with Excel::Writer::XLSX to create an Excel XLSX container file.

       From Wikipedia: The Open Packaging Conventions (OPC) is a container-file technology initially created by Microsoft to store a combination
       of XML and non-XML files that together form a single entity such as an Open XML Paper Specification (OpenXPS) document.
       <http://en.wikipedia.org/wiki/Open_Packaging_Conventions>.

       At its simplest an Excel XLSX file contains the following elements:

	    ____ [Content_Types].xml
	   |
	   |____ docProps
	   | |____ app.xml
	   | |____ core.xml
	   |
	   |____ xl
	   | |____ workbook.xml
	   | |____ worksheets
	   | | |____ sheet1.xml
	   | |
	   | |____ styles.xml
	   | |
	   | |____ theme
	   | | |____ theme1.xml
	   | |
	   | |_____rels
	   |   |____ workbook.xml.rels
	   |
	   |_____rels
	     |____ .rels

       The "Excel::Writer::XLSX::Package::Packager" class co-ordinates the classes that represent the elements of the package and writes them into
       the XLSX file.
