• Ubuntu 20.04 LTS

Packages

• mysql-8.0 - MySQL database

Details

USN-5823-1 fixed vulnerabilities in MySQL. Unfortunately, 8.0.32 introduced
a regression in MySQL Router preventing connections from PyMySQL. This
update reverts most of the changes in MySQL Router to 8.0.31 until a proper
fix can be found.

We apologize for the inconvenience.

Original advisory details:

Multiple security issues were discovered in MySQL and this update includes
new upstream MySQL versions to fix these issues.

MySQL has been updated to 8.0.32 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and
Ubuntu 22.10. Ubuntu 18.04 LTS has been updated to MySQL 5.7.41.

In addition to security fixes, the updated packages contain bug fixes, new
features, and possibly incompatible changes.
