# From http://www.libpng.org/pub/png/libpng.html (2017-01-04)
# Virtually all libpng versions through 1.6.26, 1.5.27,
# 1.4.19, 1.2.56, and 1.0.66, respectively, have a
# null-pointer-dereference bug in png_set_text_2() when an
# image-editing application adds, removes, and re-adds text
# chunks to a PNG image. (This bug does not affect pure
# viewers, nor are there any known editors that could trigger
# it without interactive user input. It has been assigned ID
# CVE-2016-10087.) The vulnerability is fixed in versions
# 1.6.27, 1.5.28, 1.4.20, 1.2.57, and 1.0.67, released on 29
# December 2016.
# Required for qt@3
