Summary
Red Hat Security Advisory: python-django security update

Notes

Topic
An update for python-django is now available for Red Hat OpenStack Platform 13 (Queens). Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Django is a high-level Python Web framework that encourages rapid development and a clean, pragmatic design. It focuses on automating as much as possible and adhering to the DRY (Don't Repeat Yourself) principle. Security Fix(es): * Incorrect HTTP detection with reverse-proxy connecting via HTTPS (CVE-2019-12781) * backtracking in a regular expression in django.utils.text.Truncator leads to DoS (CVE-2019-14232) * the behavior of the underlying HTMLParser leading to DoS (CVE-2019-14233) * SQL injection possibility in key and index lookups for JSONField/HStoreField (CVE-2019-14234) * Potential memory exhaustion in django.utils.encoding.uri_to_iri() (CVE-2019-14235) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
