Fedora 30: python2 Security Update
Summary
Python 2 is an old version of the language that is incompatible with the 3.x
line of releases. The language is mostly the same, but many details, especially
how built-in objects like dictionaries and strings work, have changed
considerably, and a lot of deprecated features have finally been removed in the
3.x line.
Note that documentation for Python 2 is provided in the python2-docs
package.
This package provides the "python2" executable; most of the actual
implementation is within the "python2-libs" package.
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.
