checkPageSlice invalid read looks to match upstream "heap-buffer-overflow"
Comment 3 Scott Gayou 2019-04-08 17:10:33 UTC 
For Red Hat Enterprise Linux 6:

```
Error: pdftops was built without CMYK support, level1sep needs it to work in this file
```

Played around with the CLI options a bit, unable to reproduce the invalid read via valgrind.

Hence, does not appear to be vulnerable.
