Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1609937]
Comment 3 Scott Gayou 2019-04-04 17:01:04 UTC 
Flaw is a failure to free memory before an exception is thrown. It looks like the exception macro just returns false and logs, thus, memory leak. (I don't believe the ImageMagick exception terminates immediately, but I did not test it.)

```
           default:
           {
             ThrowBinaryException(CorruptImageError,"CorruptImage",
               image->filename);
           }
```

All Red Hat Enterprise Linux versions look impacted by this minor memory leak.
