"CVE-2018-12564 Using the feature to add URLs in the submit page, a
user might be able to read any file on the server that is readable by
lavaserver and consists of valid yaml. So with this patch the feature
is disabled again.

For Debian 8 'Jessie', these problems have been fixed in version
2014.09.1-1+deb8u1.

We recommend that you upgrade your lava-server packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
