"It was discovered that there was a cross-site scripting (XSS)
vulnerability in velocity-tools, a collection of useful tools for the
'Velocity' template engine.

The default error page could be exploited to steal session cookies,
perform requests in the name of the victim, used for phishing attacks
and many other similar attacks.

For Debian 9 'Stretch', this problem has been fixed in version
2.0-6+deb9u1.

We recommend that you upgrade your velocity-tools packages.

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

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
