    @BlanK0 @security the fix commit says the problem occurs when the program name is very long - so probably not very exploitable, as the program name is usually set in stone.

      Symlink or copy/rename could trigger it, as long as there is a user writable area with execute perms? /home usually allows exec?

      Also some of the exec* functions allow manipulating the argv[0], so possibly another vector there.
