Description Laura Pardo 2018-01-09 21:47:52 UTC
A flaw was found on ImageMagick 7.0.7-12 Q16, a CPU exhaustion vulnerability in the function ReadDDSInfo in coders/dds.c file, which allows attackers to cause a denial of service.

Comment 1 Laura Pardo 2018-01-09 21:48:16 UTC
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.
