Description OSIDB Bzimport 2025-05-05 20:08:23 UTC 
This issue is found in the `Attach()` function when the `multiattach` flag is
set (i.e. Screen attempts to attach to a multiuser session). The function
performs a `chmod()` of the current TTY to mode 0666. The path to the current TTY is stored in the `attach_tty` string.
