[jira] Updated: (PDFBOX-518) ArrayIndexOutOfBoundsException in PDInlinedImage.java

["Andrew Duffy (JIRA)" <ji...@apache.org>]

Andrew Duffy updated PDFBOX-518:
--------------------------------

    Attachment: aioob.patch

The attached patch fixes the bug; it makes the end condition of the loop between lines 168 and 172 the same as the one between lines 174 and 181. It's consistent now - both loops will fail if the image data is bigger than expected and not fail if it's smaller.

The second loop (174 -181) looks wrong - each byte is copied into an int? Surely a rater with an int buffer expects packed RGB or ARGB data?
