+ Privilege escalation
Description
+ This is a minor information leak when running Screen with setuid-root privileges that is found in older Screen versions, as well as in version 5.0.0. The code in screen.c starting at line 849 inspects the resulting SocketPath with root privileges, and provides error messages that allow unprivileged users to deduce information about the path that would otherwise not be available. An easy way to achieve this is by using the SCREENDIR environment variable.
