CVE-2008-4099

PyDNS (aka python-dns) before 2.3.1-4 in Debian GNU/Linux does not use random source ports or transaction IDs for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than CVE-2008-1447.

Does this matter?

Lower severity and a low EPSS score (2.28%). Track it; it rarely justifies an emergency change on its own.
