Summary
Red Hat Security Advisory: rh-python35-python-jinja2 security update

Notes

Topic
An update for rh-python35-python-jinja2 is now available for Red Hat Software Collections. Red Hat Product Security has rated this update as having a security impact of Important. 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
The rh-python35-python-jinja2 package contains Jinja2, a template engine written in pure Python. Jinja2 provides a Django inspired non-XML syntax but supports inline expressions and an optional sandboxed environment. Security Fix(es): * python-jinja2: Sandbox escape due to information disclosure via str.format (CVE-2016-10745) * python-jinja2: str.format_map allows sandbox escape (CVE-2019-10906) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
