Debian 11: DLA-3863-1 Critical: Nbconvert XSS Risks Require Attention

Alvaro Muñoz from the GitHub Security Lab discovered sixteen ways to exploit a cross-site scripting vulnerability in nbconvert, a tool and library used to convert notebooks to various other formats via Jinja templates. . ------------------------------------------------------------------------- Debian LTS Advisory DLA-3863-1 This email address is being protected from spambots. You need JavaScript enabled to view it. https://www.debian.org/lts/security/ Guilhem Moulin September 02, 2024 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : nbconvert Version : 5.6.1-3+deb11u1 CVE ID : CVE-2021-32862 Alvaro Muñoz from the GitHub Security Lab discovered sixteen ways to exploit a cross-site scripting vulnerability in nbconvert, a tool and library used to convert notebooks to various other formats via Jinja templates. When using nbconvert to generate an HTML version of a user-controllable notebook, it is possible to inject arbitrary HTML which may lead to cross-site scripting (XSS) vulnerabilities if these HTML notebooks are served by a web server without tight Content-Security-Policy (e.g., nbviewer). * GHSL-2021-1013: XSS in notebook.metadata.language_info.pygments_lexer; * GHSL-2021-1014: XSS in notebook.metadata.title; * GHSL-2021-1015: XSS in notebook.metadata.widgets; * GHSL-2021-1016: XSS in notebook.cell.metadata.tags; * GHSL-2021-1017: XSS in output data text/html cells; * GHSL-2021-1018: XSS in output data image/svg+xml cells; * GHSL-2021-1019: XSS in notebook.cell.output.svg_filename; * GHSL-2021-1020: XSS in output data text/markdown cells; * GHSL-2021-1021: XSS in output data application/javascript cells; * GHSL-2021-1022: XSS in output.metadata.filenames image/png and image/jpeg; * GHSL-2021-1023: XSS in output data image/png and image/jpeg cells; * GHSL-2021-1024: XSS in output.metadata.width/height image/png and image/jpeg; * GHSL-2021-1025: XSSin output data application/vnd.jupyter.widget-state+ json cells; * GHSL-2021-1026: XSS in output data application/vnd.jupyter.widget-view+ json cells; * GHSL-2021-1027: XSS in raw cells; and * GHSL-2021-1028: XSS in markdown cells. Some of these vulnerabilities, namely GHSL-2021-1017, -1020, -1021, and -1028, are actually design decisions where text/html, text/markdown, application/JavaScript and markdown cells should allow for arbitrary JavaScript code execution. These vulnerabilities are therefore left open by default, but users can now opt-out and strip down all JavaScript elements via a new HTMLExporter option `sanitize_html`. For Debian 11 bullseye, this problem has been fixed in version 5.6.1-3+deb11u1. We recommend that you upgrade your nbconvert packages. For the detailed security status of nbconvert please refer to its security tracker page at: https://security-tracker.debian.org/tracker/source-package/nbconvert Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS . The DLA-4872-3 notice outlines critical SQL injection issues within the DataHandler module, recommending an immediate patch for user protection..
