Description

USN-4441-1 fixed vulnerabilities in MySQL. The new upstream version changed compiler options and caused a regression in certain scenarios. This update fixes the problem.

Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to fix these issues. MySQL has been updated to 8.0.21 in Ubuntu 20.04 LTS. Ubuntu 16.04 LTS and Ubuntu 18.04 LTS have been updated to MySQL 5.7.31. In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes. Please see the following for more information: https://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-31.html https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-21.html https://www.oracle.com/security-alerts/cpujul2020.html

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
