The MultiPartParser, UploadedFile and FieldFile classes allowed directory-traversal via uploaded files with suitably crafted file names. In order to mitigate this risk, stricter basename and path sanitation is now applied. Specifically, empty file names and paths with dot segments are rejected. For Debian 9 "Stretch", this problem has been fixed in version 1:1.10.7-2+deb9u13. We recommend that you upgrade your python-django packages. For the detailed security status of python-django please refer to its security tracker page at: https://security-tracker.debian.org/tracker/python-django 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 - -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEwv5L0nHBObhsUz5GHpU+J9QxHlgFAmCTtQ0ACgkQHpU+J9Qx Hlh0Wg/8DGkgyGOP8oeIWwy7uU3+HycLgB9Z1KvQ3B05H3Bj4sgWBsU3jJ7r9raI VbC/A3S5aauL3AfjMK4Akd4pkMYhDMBhRCioHrPqMf9dpJvQzKZMU+MhDBlGoPks UzlZv6uAbgafasXKIY2jdTbOwbjz5F6+prP4+CoYhkibkyY/R8MnpDKZgnE7i1oS GS5E4qvCyaP2bqoXPEN8uwbV/ZTBYZ45TRTOzTfOXjevjFJBHch7dCwYVyxRaClG X3Me1cC2lFE2N8FcZZgv5MPysAl83PFbc5sTKntnGKcZSN83Th0iSkwOFpD2sMDE jZeEGhuZBkPZmZkKsBtIWYe91ZgWqQzifdjWA0hPJ8ZXTsA11mkCGCJRsw9swxrz rjf+EN7OwKUc627oyEupegTSLd0VQ/n5pE7m27cCMBWrO5CU96/65AJwGWjmd3ZH jTNa0Mz5npxSfTooDv7PoWiMBCgPqvhdj/UC3cyPAwhFaAfzFy9rnCrg7l+wY3QP JS9RfylAOs9Vr9Dwdh+GDkIl6NnjLdZ9mqmvImZb2MRXZOtKEVQSCskMwT5Zu5Iu a0OWC+QUhvEi6LVm+CgWnDSC/eSrYwepJQoGDbp9wKAMQnesg1TnvhxX87GqjE6a t9zSsOgJtnBaPvKNEB4Yi3TmyIiTE6Eccc46hgU+VP+NfwlJdw8= =2YmT - -----END PGP SIGNATURE----- - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
