Package : python-django
Version : 1:1.11.29-1+deb10u2
CVE IDs : CVE-2020-24583 CVE-2020-24584 CVE-2021-3281
CVE-2021-23336 CVE-2022-34265
Debian Bugs : 969367 981562 983090 1014541

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 attach 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.
