           operand=ReadBlobByte(image);
+          if (opcode == EOF)
+            ThrowRLEException(CorruptImageError,"UnexpectedEndOfFile");

This looks suspicious to me. There are more such occurences.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.
