Fedora 30: FEDORA-2019-0c91ce7b3c Critical: Python 2 Segfault Issues

The python2-docs package contains documentation on the Python 2

programming language and interpreter.

Install the python2-docs package if you'd like to use the documentation

for the Python 2 language.

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](rc1.rst)). Fixes the following CVEs: *

[CVE-2019-5010](https://access.redhat.com/security/cve/cve-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/cve-2013-1752): Change

use of readline() in `imaplib.IMAP4_SSL` to limit line length.

([CVE-2018-14647](https://access.redhat.com/security/cve/cve-2018-14647) 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.

[ 1 ] Bug #1643450 - Python 2 is built against an old OpenSSL (1.0.1) while 1.1.1 is available in F29
