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.
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.
