[jira] [Created] (TIKA-1322) XML file parse errors within archives trigger Zip bomb detection

Matthias Krueger created TIKA-1322:
--------------------------------------

             Summary: XML file parse errors within archives trigger Zip bomb detection
                 Key: TIKA-1322
                 URL: https://issues.apache.org/jira/browse/TIKA-1322
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 1.5
            Reporter: Matthias Krueger
            Priority: Minor


Tika parses XML input using org.apache.tika.parser.xml.XMLParser. XMLParser opens a "p" tag before a SAXParser's output of the input XML is appended. A possible SAXException during parsing is rethrown but the opened "p" tag not closed. The Zip bomb detection in SecureContentHandler relies on consistent starting and closing of elements. With the current behaviour of XMLParser it will be triggered, for example, if an archive contains 10 (SecureContentHandler#maxPackageEntryDepth) invalid XML files.
