CVE-2020-13254
Description
A flaw was found in Django, where the memcached backend does not perform key validation and passes malformed keys. This flaw causes a key collision and potential data leakage. The highest threat from this vulnerability is to confidentiality.
Statement
Red Hat Satellite 6 ships affected python-django, however, it does not use memcached implementation in product code hence not vulnerable to this flaw.
Red Hat Update Infrastructure 3 ships an affected version of python-django, however it does not use memcached as a cache backend and it is not vulnerable to this flaw.
Red Hat Ceph Storage(RHCS) ships an affected version of python-django used with calamari and graphite which are no longer supported, hence the django package will not be fixed for RHCS.
