python-django package fixes multiple vulnerabilities","description":"Updated python-django package fixes security vulnerabilities:\n\nRainer Koirikivi discovered a directory traversal vulnerability with 'ssi'\ntemplate tags in python-django, a high-level Python web development framework.\nIt was shown that the handling of the 'ALLOWED_INCLUDE_ROOTS' setting, used to\nrepresent allowed prefixes for the {% ssi %} template tag, is vulnerable to a\ndirectory traversal attack, by specifying a file path which begins as the\nabsolute path of a directory in 'ALLOWED_INCLUDE_ROOTS', and then uses relative\npaths to break free.  To exploit this vulnerability an attacker must be in a\nposition to alter templates on the site, or the site to be attacked must have\none or more templates making use of the 'ssi' tag, and must allow some form of\nunsanitized user input to be used as an argument to the 'ssi' tag\n(CVE-2013-4315).\n\nDjango before 1.4.8 allows for denial-of-service attacks through repeated\nsubmission of large passwords, tying up server resources in the expensive\ncomputation of the corresponding hashes (CVE-2013-1443).\n","status":"published","published":"2013-09-19T09:45:04Z","modified":"2026-04-16T06:26:17.623743456Z","updated_at":"2026-11-02T15:49:39.121227Z"},{"id":"PYSEC-2013-18","description":"The authentication framework (django.contrib.auth) in Django 1.4.x before 1.4.8, 1.5.x before 1.5.4, and 1.6.x before 1.6 beta 4 allows remote attackers to cause a denial of service (CPU consumption) via a long password which is then hashed.","status":"published","published":"2013-09-23T20:55:00Z","modified":"2026-06-10T17:00:54.25712694Z","updated_at":"2026-11-02T15:52:51.645172Z"}]}}
