Fedora 34: 2021-303f6623fa Moderate: GDM Directory Traversal Issue

GDM, the GNOME Display Manager, handles authentication-related backend

functionality for logging in a user and unlocking the user's session after

it's been locked. GDM also provides functionality for initiating user-switching,

so more than one user can be logged in at the same time. It handles

graphical session registration with the system for both local and remote

sessions (in the latter case, via the XDMCP protocol). In cases where the

session doesn't provide it's own display server, GDM can start the display

server on behalf of the session.
