  script_tag(name:"insight", value:"Multiple vulnerabilities were discovered in Django, a popular Python-based web development framework:

CVE-2020-24583: Fix incorrect permissions on intermediate-level directories on Python 3.7+. FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories created in the process of uploading files and to intermediate-level collected static directories when using the collectstatic management command. You should review and manually fix permissions on existing intermediate-level directories.

CVE-2020-24584: Correct permission escalation vulnerability in intermediate-level directories of the file system cache. On Python 3.7 and above, the intermediate-level directories of the file system cache had the system's standard umask rather than 0o077 (no group or others permissions).

CVE-2021-3281: Fix a potential directory-traversal exploit via archive.extract(). The django.utils.archive.extract() function, used by startapp --template and startproject --template, allowed directory traversal via an archive with absolute paths or relative paths with dot segments.

CVE-2021-23336: Prevent a web cache poisoning attack via 'parameter cloaking'. Django contains a copy of urllib.parse.parse_qsl() which was added to backport some security fixes. A further security fix has been issued recently such that parse_qsl() no longer allows using ',' as a query parameter separator by default.

CVE-2022-34265: The Trunc() and Extract() database functions were subject to a potential SQL injection attack if untrusted data was used as a value for the 'kind' or 'lookup_name' parameters. Applications that constrain the choice to a known safe list were unaffected.

For Debian 10 Buster, these problems have been fixed in version 1:1.11.29-1+deb10u2.

We recommend that you upgrade your python-django packages.
