Updated python-django package fixes security vulnerabilities

Publication date: 16 Jul 2021
Type: security
Affected Mageia releases : 8
CVE: CVE-2021-28658 , CVE-2021-31542 , CVE-2021-32052 , CVE-2021-33203 , CVE-2021-33571 , CVE-2021-35042


In Django 2.2 before 2.2.20, 3.0 before 3.0.14, and 3.1 before 3.1.8,
MultiPartParser allowed directory traversal via uploaded files with suitably
crafted file names. Built-in upload handlers were not affected by this
vulnerability (CVE-2021-28658).

In Django 2.2 before 2.2.21, 3.1 before 3.1.9, and 3.2 before 3.2.1,
MultiPartParser, UploadedFile, and FieldFile allowed directory traversal via
uploaded files with suitably crafted file names (CVE-2021-31542).

In Django 2.2 before 2.2.22, 3.1 before 3.1.10, and 3.2 before 3.2.2 (with
Python 3.9.5+), URLValidator does not prohibit newlines and tabs (unless the
URLField form field is used). If an application uses values with newlines in
an HTTP response, header injection can occur. Django itself is unaffected
because HttpResponse prohibits newlines in HTTP headers (CVE-2021-32052).

Django before 2.2.24, 3.x before 3.1.12, and 3.2.x before 3.2.4 has a potential
directory traversal via django.contrib.admindocs. Staff members could use the
TemplateDetailView view to check the existence of arbitrary files.
Additionally, if (and only if) the default admindocs templates have been
customized by application developers to also show file contents, then not only
the existence but also the file contents would have been exposed. In other
words, there is directory traversal outside of the template root directories

In Django 2.2 before 2.2.24, 3.x before 3.1.12, and 3.2 before 3.2.4,
URLValidator, validate_ipv4_address, and validate_ipv46_address do not prohibit
leading zero characters in octal literals. This may allow a bypass of access
control that is based on IP addresses. (validate_ipv4_address and
validate_ipv46_address are unaffected with Python 3.9.5+..) (CVE-2021-33571).

Django 3.1.x before 3.1.13 and 3.2.x before 3.2.5 allows QuerySet.order_by
SQL injection if order_by is untrusted input from a client of a web application

python-django package is updated to 3.1.13 version to fix these security
issues among other upstream bugfixes, see upstream release notes.
