New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Fedora host is missing one or more security updates.

Description

Update legacy Python to 2.7.16. Most significant improvement is that is builds against OpenSSL 1.1.1. See [upstream release announcement](https://www.python.org/downloads/release/python-2716/) and [changelog](https://github.com/python/cpython/blob/2.7/Misc/NEWS.d/2.7 .16.rst) (+ [rc1 changelog](https://github.com/python/cpython/blob/2.7/Misc/NEWS.d/2.7.
16rc1.rst)).

Fixes the following CVEs :

- [CVE-2019-5010](https://access.redhat.com/security/cve/c ve-2019-5010) Fix a NULL pointer deref in ssl module.
The cert parser did not handle CRL distribution points with empty DP or URI correctly. A malicious or buggy certificate can result into segfault. Vulnerability (TALOS-2018-0758) reported by Colin Read and Nicolas Edet of Cisco.

- [CVE-2013-1752](https://access.redhat.com/security/cve/c ve-2013-1752): Change use of readline() in `imaplib.IMAP4_SSL` to limit line length.

([CVE-2018-14647](https://access.redhat.com/security/cve/cve-2018-1464 7) is listed in upstream changelog, but it was already backported in Fedora.)

Note that Python 2 is deprecated in Fedora 30 and users are advised to switch to Python 3. Upstream support of Python 2 ends on 2020-01-01.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python2 and / or python2-docs packages.
