Discussion

GNOME Foundation GDM Configure Login Manager Authentication Bypass Vulnerability

GDM is susceptible to an authentication-bypass vulnerability when users try to access the 'Configure Login Manager' option.

This issue allows local attackers to execute the 'Configure Login Manager' option with superuser privileges without entering valid superuser credentials. This allows them to make unauthorized configuration changes, which in turn grants them administrative access to affected computers, facilitating their complete compromise.
