"It was discovered that there was a potential arbitrary code execution
vulnerability in velocity, a Java-based template engine for writing
web applications. It could be exploited by applications which allowed
untrusted users to upload/modify templates.

For Debian 9 'Stretch', this problem has been fixed in version
1.7-5+deb9u1.

We recommend that you upgrade your velocity packages.

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

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."
