On Debian, we're going to use apt, which is the newest and, in my opinion, friendliest tool.
Unlike YUM, we can easily and independently update the list of available packages:
$ sudo apt updateIgn:1 http://deb.debian.org/debian stretch InReleaseHit:2 http://deb.debian.org/debian stretch ReleaseHit:4 http://security.debian.org/debian-security stretch/updates InReleaseReading package lists... DoneBuilding dependency tree Reading state information... Done15 packages can be upgraded. Run 'apt list --upgradable' to see them.
Note that it only updates its list, not the programs themselves.
Now, we can look for specific information by using the suggested command:
$ apt list --upgradable linux-image*Listing... Donelinux-image-4.9.0-7-amd64/stable ...
