More information:

Several vulnerabilities have been discovered in jupyter-notebook.

  • CVE-2018-8768

    A maliciously forged notebook file can bypass sanitization to execute Javascript in the notebook context. Specifically, invalid HTML is fixed by jQuery after sanitization, making it dangerous.

  • CVE-2018-19351

    allows XSS via an untrusted notebook because nbconvert responses are considered to have the same origin as the notebook server.

  • CVE-2018-21030

    jupyter-notebook does not use a CSP header to treat served files as belonging to a separate origin. Thus, for example, an XSS payload can be placed in an SVG document.

For Debian 9 stretch, these problems have been fixed in version 4.2.3-4+deb9u1.

We recommend that you upgrade your jupyter-notebook packages.
