There's a bunch of CVEs in libtiff 4.0.9:

CVE-2018-7456 is a null pointer dereference, 2018-8905 is a heap overflow, and the others are supposedly only DoS vulnerabilities. CVE-2018-8905 has got a CVSS v3.0 base score of 8.8, hence I've set the severity to "high".

All five CVEs have seemingly already been fixed in upstream's git quite some time ago (CVE-2018-8905 and CVE-2018-10963 on 2018-05-12, for example), yet upstream has not cared yet to make a new release version. I suggest to follow upstream's git master until there is an actual release.

Debian has released an advisory on this as well:
This task depends upon
