[Samba] Heads-up: Upcoming Samba security releases

[Douglas Bagnall]

This is a heads-up that there will be Samba security updates for 4.21, 
4.22, and 4.23 on Wednesday, October 15, 2025. Please make sure that 
your Samba servers will be updated soon after the release!

Impacted component:
  - AD DC (CVSS 10, High, when using a very unusual configuration)
  - File services (CVSS 4.3, Low, in a widely used configuration)

The AD DC bug will affect very few, possibly zero, users.

cheers,
