The unique ID's perhaps are containerid version, runc version and ID version. If somebody comes to know of these details, could there be problems?

Generally you wouldn't want to share any piece of enumeration info to anyone.. However if you need to share this with a vendor, I don't see a problem sharing this specific log file.

Not directly, there's no passwords or keys that could be used to log in for example. It would be useful for someone looking to crack your system as it gives them a lot of handy information, for example:

  • Operating system type
  • OS kernel version
  • Security options
  • Plugins

These would remove a lot of the guesswork, so you'd want to limit who would have access to this report to those that need it.
