Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1532846]

Comment 2 Scott Gayou 2019-04-04 19:13:31 UTC

This one is really borderline:

```
time convert poc /dev/null
convert: unexpected end-of-file `poc': No such file or directory @ error/dds.c/ReadDDSImage/403.

real	1m1.518s
user	1m1.439s
sys	0m0.044s
```

Does take one minute or so tested across multiple machines. CPU-exhaustion, a valid DOS in this case? Seems reasonable I suppose.
