[security] Go 1.24.3 and Go 1.23.9 are released

[Cherry Mui]

Hello gophers,

We have just released Go versions 1.24.3 and 1.23.9, minor point releases.

The Go 1.24.3 minor release includes 1 security fix following the security policy:

• os: Root permits access to parent directory
  
  It was possible to improperly access the parent directory of an os.Root
  by opening a filename ending in "../". For example, Root.Open("../") would
  open the parent directory of the Root. This escape only permits opening
  the parent directory itself, not ancestors of the parent or files contained
  within the parent.
  
  Root now correctly returns an error in this case.
  
  This is CVE-2025-22873 and Go issue https://go.dev/issue/73555.
  
  Thanks to Dan Sebastian Thrane of SDU eScience Center for reporting this issue.

This security fix only applies to Go 1.24.x releases. Go 1.23.x releases are not affected by this.
