Subject: python-django: CVE-2023-23969 Potential denial-of-service via Accept-Language headers

Date: Wed, 01 Feb 2023 07:53:11 -0800

Package: python-django
Version: 1:1.11.29-1+deb10u5
X-Debbugs-CC: team@security.debian.org
Severity: grave
Tags: security

Hi,

The following vulnerability was published for python-django.

  CVE-2023-23969: Potential denial-of-service via Accept-Language headers

  The parsed values of Accept-Language headers are cached in
  order to avoid repetitive parsing. This leads to a potential
  denial-of-service vector via excessive memory usage if large header
  values are sent.

  In order to avoid this vulnerability, the Accept-Language header is
  now parsed up to a maximum length.

  Thanks to Mithril for the report.

  This issue has severity "moderate" according to the Django security
  policy.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
