Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

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.'
