JSON

Integer underflow in the png_check_keyword function in pngwutil.c in libpng
0.90 through 0.99, 1.0.x before 1.0.66, 1.1.x and 1.2.x before 1.2.56,
1.3.x and 1.4.x before 1.4.19, and 1.5.x before 1.5.26 allows remote
attackers to have unspecified impact via a space character as a keyword in
a PNG image, which triggers an out-of-bounds read.
