As far as we can tell, what you mean is that gif2webp is a
command-line program that only operates on one GIF input file, and if
there's crafted EXTENSION_RECORD_TYPE data, the program will crash
with a NULL pointer derreference. That would not be a security impact
for purposes of CVE. The user can work around the bug by not running
gif2webp again on the crafted file.
