CVE-2017-6363

Published: 27 February 2020

** DISPUTED ** In the GD Graphics Library (aka LibGD) through 2.2.5, there is a heap-based buffer over-read in tiffWriter in gd_tiff.c. NOTE: the vendor says "In my opinion this issue should not have a CVE, since the GD and GD2 formats are documented to be 'obsolete, and should only be used for development and testing purposes.'"
