I can confirm this problem on Ubuntu 16.04 and ghostscript 9.26~dfsg+0-0ubuntu0.16.04.1:

$ gs --version
9.26
$ convert "confidential.pdf[0]" confidential.png
convert: FailedToExecuteCommand `"gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -dFirstPage=1 -dLastPage=1 "-sOutputFile=/tmp/magick-12412a591aAW0c1rp%d" "-f/tmp/magick-12412pbD9WU9tgyvz" "-f/tmp/magick-12412_OoIhBmXubzJ"' (-1) @ error/delegate.c/ExternalDelegateCommand/461.
convert: no images defined `confidential.png' @ error/convert.c/ConvertImageCommand/3210.

The problem doesn't happen with ghostscript 9.25~dfsg+1-0ubuntu0.16.04.3:

$ dpkg --install libgs9_9.25~dfsg+1-0ubuntu0.16.04.3_amd64.deb libgs9-common_9.25~dfsg+1-0ubuntu0.16.04.3_all.deb ghostscript_9.25~dfsg+1-0ubuntu0.16.04.3_amd64.deb ghostscript-x_9.25~dfsg+1-0ubuntu0.16.04.3_amd64.deb
$ gs --version
9.25
$ convert "confidential.pdf[0]" confidential.png
$ identify confidential.png
confidential.png PNG 595x842 595x842+0+0 8-bit sRGB 22.5KB 0.000u 0:00.000

Not every PDF is affected by this problem.
