Summary	0000096: MRMLIdImageIO crashes when shared object plugin writes a (true) 2D image
Description	MRMLIdImageIO crashes when a shared object plugin writes a true 2D image (as opposed to a degenerate 3D image) to the MRML scene. The error is in MRMLIdImageIO::WriteInformation() which assumes a 3D image. Loops to copy the directions, spacing, origin, etc. go for "i < 3" (buffer overflow).
Additional Information	Since Slicer is a 3D application, we should initialize local variables to a valid state for 3D. Then overwrite pieces of that information based on the plugin. The "read" direction may not have this issue. But we should verify that we do not have uninitialized variables or buffer overflows.
Tags	No tags attached.
