That bug has been potentially exploitable[1], but the GD extension was not affected by that, because `gdImageBmpPtr()` is never called. Still it seems to be reasonable to port the fix; if only to keep bundled and external libgd synced. [1] <GHSA-hc3p-jvff-jfw5>

Yeah, but I like to stay as close to upstream as possible (I still haven't completely lost hope that at some point in time we can unbundle libgd). And there we have https://github.com/libgd/libgd/blob/77adfd27f776352e8095d98ef4902c28975d19af/src/gd_bmp.c#L88-L99
