Summary: An update for python is now available for Red Hat Enterprise Linux 7.5 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux ComputeNode EUS (v. 7.5) - x86_64 Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.5) - x86_64 Red Hat Enterprise Linux Server EUS (v. 7.5) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 7.5) - ppc64, ppc64le, s390x, x86_64 3. Description: Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * python: DOS via regular expression backtracking in difflib.IS_LINE_JUNK method in difflib (CVE-2018-1061) * python: Missing salt initialization in _elementtree.c module (CVE-2018-14647) * python: CRLF injection via the query part of the url passed to urlopen() (CVE-2019-9740) * python: CRLF injection via the path part of the url passed to urlopen() (CVE-2019-9947) * 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. 4.
