It was discovered that there was a arbitrary code execution vulnerability in grunt, a JavaScript task runner. This was possible due to the unsafe loading of YAML documents.
For Debian 9 ‘Stretch’, this problem has been fixed in version 1.0.1-5+deb9u1.
We recommend that you upgrade your grunt packages.
For the detailed security status of grunt please refer to its security tracker page at: https://security-tracker.debian.org/tracker/grunt
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.
