Summary
Red Hat Security Advisory: python-virtualenv security update

Notes

Topic
An update for python-virtualenv is now available for Red Hat Enterprise Linux 7. 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 virtualenv tool creates isolated Python environments. The virtualenv tool is a successor to workingenv, and an extension of virtual-python. Security Fix(es): * python-urllib3: Cross-host redirect does not remove Authorization header allow for credential exposure (CVE-2018-20060) * python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236) * python-requests: Redirect from HTTPS to HTTP does not remove Authorization header (CVE-2018-18074) 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.
