Amazing. PNG is a recent enough graphics file format that I would have expected even Microsoft to heavily bounds- check any code that reads it

Not sure where you get this "recent enough" part. PNGS were available, royalty free circa 1996. We used them in a mud I was part of then.

They implemented the original basic PNG format, then as usual with microsoft. Left it in that half-assed state rather than actually fully implement the format. PNG supports transparency and animation similar to GIFs. From what I understand, Microsoft still doesn't support either.

Which is long after MS would have had corporate awareness
of buffer overflow exploits. They did, after all, include
anti-virus support in DOS 6.x years before that.

When did MS implement PNG support in Windows?
