HSLFSlideShow in Apache POI before 3.11 allows remote attackers to cause a denial of service (infinite loop and deadlock) via a crafted PPT file.

The OPC SAX setup in Apache POI before 3.10.1 allows remote attackers to read arbitrary files via an OpenXML file containing an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

Apache POI before 3.10.1 and 3.11.x before 3.11-beta2 allows remote attackers to cause a denial of service (CPU consumption and crash) via a crafted OOXML file, aka an XML Entity Expansion (XEE) attack.

The XLSX2CSV example in Apache POI before 3.14 allows remote attackers to read arbitrary files via a crafted OpenXML document containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

The UnhandledDataStructure function in hwpf/model/UnhandledDataStructure.java in Apache POI 3.8 and earlier allows remote attackers to cause a denial of service (OutOfMemoryError exception and possibly JVM destabilization) via a crafted length value in a Channel Definition Format (CDF) or Compound File Binary Format (CFBF) document.

When using the tool XSSFExportToXml to convert user-provided Microsoft Excel documents, a specially crafted document can allow an attacker to read files from the local filesystem or from internal network resources via XML External Entity (XXE) Processing.

Apache POI is vulnerable to Denial of Service Attacks through infinite loops while parsing crafted WMF, EMF, MSG and macros or Out of Memory Exceptions while parsing crafted DOC, PPT and XLS.

This package allows remote attackers to cause a denial of service (CPU consumption) via a specially crafted OOXML file, aka an XML Entity Expansion (XEE) attack.
