An update for python3 is now available for openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1264 Final 1.0 1.0 2021-07-10 Initial 2021-07-10 2021-07-10 openEuler SA Tool V1.0 2021-07-10 python3 security update An update for python3 is now available for openEuler-20.03-LTS-SP1. Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces. Security Fix(es): There s a flaw in Python 3 s pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7.(CVE-2021-3426) An update for python3 is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
