"An issue has been found in highlight.js, a JavaScript library for
syntax highlighting. If a website or application renders user provided
data it might be affected by a Prototype Pollution. This might result
in strange behavior or crashes of applications that do not correctly
handle unknown properties.

For Debian 9 stretch, this problem has been fixed in version
8.2+ds-5+deb9u1.

We recommend that you upgrade your highlight.js packages.

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

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."
