- Fix CVE-2018-14553 : gdImageClone in gd.c in libgd 2.1.0-rc2 through
2.2.5 has a NULL pointer dereference allowing attackers to crash an
application via a specific function call sequence.
- Fix CVE-2019-6977: gdImageColorMatch in gd_color_match.c in the GD
Graphics Library (aka LibGD) 2.2.5, as used in the imagecolormatch
function in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14,
and 7.3.x before 7.3.1, has a heap-based buffer overflow. This can be
