"Apache HTTP Server versions before 2.4.32 uses src:uwsgi where a flaw
was discovered. The uwsgi protocol does not let us serialize more than
16K of HTTP header leading to resource exhaustion and denial of
service.

For Debian 9 stretch, this problem has been fixed in version
2.0.14+20161117-3+deb9u3.

We recommend that you upgrade your uwsgi packages.

For the detailed security status of uwsgi please refer to its security
tracker page at: https://security-tracker.debian.org/tracker/uwsgi

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
