Summary
Red Hat Security Advisory: python-urllib3 security update

Notes

Topic
An update for python-urllib3 is now available for Red Hat Enterprise Linux 8. 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
The python-urllib3 package provides the Python HTTP module with connection pooling and file POST abilities. Security Fix(es): * python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236) * python-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324) 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. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.1 Release Notes linked from the References section.
