## Description

libpng before 1.2.37 does not properly parse 1-bit interlaced images with
width values that are not divisible by 8, which causes libpng to include
uninitialized bits in certain rows of a PNG file and might allow remote
attackers to read portions of sensitive memory via "out-of-bounds pixels"
in the file.
