Synopsis

The remote Scientific Linux host is missing a security update.

Description

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)

Solution

Update the affected python3-pip package.
