Summary: [PATCH] Picture.fillRawImageContent -
ArrayIndexOutOfBoundsException
Product: POI
Version: 3.8-dev

Status: NEW
Severity: major

Component: HWPF
AssignedTo: [email protected]

Patch for issue
Found a handful of Word files that cause ArrayIndexOOB. (Unable to attach
sample due to sensitive nature of files).
Patch included, essentially the pictureBytesStartOffset used for a
System.arraycopy() is sometimes set to a negative value.
Fix uses an existing less-than check but also makes sure it's greater than zero
before using the new value rather than the default PICTF1BlockOffset.
Stack Trace: (POI-3.8-beta4)
