Debian DLA-2432-1 : jupyter-notebook security update

high Nessus Plugin ID 143107

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

For the detailed security status of jupyter-notebook please refer to its security tracker page at:

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.
