* python: urllib: Regular expression DoS in AbstractBasicAuthHandler (CVE-2021-3733)

* python-lxml: Missing input sanitization for formaction HTML5 attributes may lead to XSS (CVE-2021-28957)

* python-ipaddress: Improper input validation of octal strings (CVE-2021-29921)

* python-urllib3: ReDoS in the parsing of authority part of URL (CVE-2021-33503)

* python-pip: Incorrect handling of unicode separators in git references (CVE-2021-3572)

* python: urllib: HTTP client possible infinite loop on a 100 Continue response (CVE-2021-3737)

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 8.5 Release Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL python39:3.9 / python39-devel:3.9 packages based on the guidance in RHSA-2021:4160.
