Package        : jupyter-notebook
Version        : 4.2.3-4+deb9u1
CVE ID         : CVE-2018-8768 CVE-2018-19351 CVE-2018-21030
Debian Bug     : 893436 917409

Several vulnerabilities have been discovered in jupyter-notebook.


    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.


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


    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

We recommend that you upgrade your jupyter-notebook packages.
