Some web sites talk about their fonts files as being clean or checked.
Does this mean some types of font file can be infected with malware?

Fonts can be malformed in a number of ways that create problems for the
user. Probably the most obvious is an older font that is far enough out
of spec that recent versions of Windows will refuse to load it. I'm not
aware of fonts carrying malware, so I would just read those as product
benefit claims--our fonts are high quality, basically.

I remember a bug in a webbrowser causing a buffer overflow with specially
crafted font files. Now, that was Netscape 4.0, which is quite a long time ago.
Without a bug, there's no specified way to include executable code in font
files.

Font files are none malicious.
However, there are Trojans that will hide in the Windows font folder.

No, but I've accidentally created some otf fonts that, if
double-clicked, for some inexplicable reason result in a BSOD (Blue
Screen of Death)! No harm done, just very annoying.
