The OpenSSH client has a lot of very powerful features for tunneling applications through a SSH connections and is one of my favorite tools for quick-and-dirty network plumbing tasks. It can be very useful for fixing/bypassing connectivity issues (caused by NATs, firewalls), accessing internal networks. This post is an overview of the different tunneling options available in OpenSSH. This is inteded as a reference to use when I am explaining (every so often) how to use SSH for tunneling.

In Debian kitty
package, the kitty-open.desktop
file would associate kitty +open
with several MIME types. This could be used to arbitrary trigger code execution by serving a file with such a MIME type.
This has been introduced in kitty in 73a197fcd (2022-02-06) released as part of v0.24.3. This has been fixed in v0.26.5-5 of the Debian kitty package. Fixed upstream in 537cabca7 released in v0.29.0. Other distributions such as Ubuntu Lunar are still impacted.
