Debian DLA-2511-1 : highlight.js security update

high Nessus Plugin ID 144666

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected packages.
