DO NOT REPLY [Bug 51992] New: VariantSupport confuses bytes and
chars for LPWSTR
https://issues.apache.org/bugzilla/show_bug.cgi?id=51992
Bug #: 51992
Summary: VariantSupport confuses bytes and chars for LPWSTR
Product: POI
Version: 3.8-dev
Platform: PC
Status: NEW
Severity: normal
Priority: P2
Component: HSLF
AssignedTo: dev@poi.apache.org
ReportedBy: jsg8pitt@yahoo.com
Classification: Unclassified
Created attachment 27727
--> https://issues.apache.org/bugzilla/attachment.cgi?id=27727
patch
A coworker and I ran into some ArrayIndexOutOfBoundsExceptions while
processing ppt files using POI (by way of Tika), and tracked the problem
down to some of the code in VariantSupport.
I can't attach the actual ppt files that we had that provoked the problem, but
I'll see if can create some new ones.

Sadly, I cannot recreate the issue in a new ppt -- a new one created in
libreoffice doesn't display the issue, and if I make changes to the one that I
have to anonymize it then the saved version doesn't display the problem either.

No, that won't work. If I open edit and save the file, then it no longer
displays the problem.
I will try to track down the file again, and if I can find it, I would be
willing to set up an appointment for a developer to ssh into my machine and
work with the file here.
In the meantime, though, I'm curious if there are any test files for the
project for which the aforementioned code is actually correct -- it seems to me
that it's just written incorrectly and wouldn't work for any test file that
exercises the code (but, of course, these being office formats, I wouldn't be
surprised if I'm completely wrong).

Which version of Tika and POI?
Can you obfuscate the problematic ppt file ? The problem is with reading the
document properties and this is all we need to track the problem.
Open the problematic ppt file in PowerPoint, delete all content from the slides
and save. Is the file readable by Tika ?
