Thank you very much.

It appears that this is not how python is maintained, as all python modules and packages have to be rebuilt for each major version, so fixes are applied to each supported major version e.g 3.9!

for a few other packages see:


so 3.{8,9}.19+ should fix all currently known security issues with 3.{8,9}; other releases are required for newer versions.

And 3.11.5 has issues, 3.11.9 is fixed: let your co IT know this!

Please note also that some vulnerabilities are specific to only certain platforms and capabilities e.g. Linux:
