* python: Undocumented local_file protocol allows remote attackers to bypass protection mechanisms (CVE-2019-9948)

* python: DOS via regular expression catastrophic backtracking in apop() method in pop3lib (CVE-2018-1060)

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.

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