Summary
Red Hat Security Advisory: python-pip security update

Notes

Topic
An update for python-pip 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
pip is a package management system used to install and manage software packages written in Python. Many packages can be found in the Python Package Index (PyPI). pip is a recursive acronym that can stand for either "Pip Installs Packages" or "Pip Installs 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-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324) * 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. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.2 Release Notes linked from the References section.
