Package : python-django Version : 1:1.11.29-1+deb10u11 CVE IDs : CVE-2021-28658 CVE-2021-31542 CVE-2021-33203 CVE-2021-33571 Debian Bugs : 986447 988053 989394

It was discovered that there were a number of issues in Django, a popular Python-based web development framework:

* CVE-2021-28658: Prevent a directory traversal issue which could have been exploited by maliciously crafted filenames. However, the built-in upload handlers were not affected by this vulnerability.
(#986447)

* CVE-2021-31542: Fix a potential directory-traversal vulnerability that could have been exploited by uploaded files. 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. (#988053)

* CVE-2021-33203: Prevent a potential directory traversal via admindocs. Staff members could use the admindocs TemplateDetailView view to check the existence of arbitrary files.
Additionally, if (and only if) the default admindocs templates have been customized by the developers to also expose the file contents, then not only the existence but also the file contents would have been exposed. As a mitigation, path sanitation is now applied and only files within the template root directories can be loaded. (#989394)

* CVE-2021-33571: Prevent possible SSRF, RFI (Remote File Inclusion) and LFI (Local File Inclusion) attacks, since validators accepted leading zeros in IPv4 addresses URLValidator, validate_ipv4_address() and validate_ipv46_address() did not prohibit leading zeros in octal literals. (#989394)

For Debian 10 buster, these problems have been fixed in version 1:1.11.29-1+deb10u11.

We recommend that you upgrade your python-django packages.
