		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">python3 security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for python3 is now available for openEuler-20.03-LTS-SP1.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">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):

An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating optimisations were possible in the accumulator variable in hmac.compare_digest.(CVE-2022-48566)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for python3 is now available for openEuler-20.03-LTS-SP1.
