REDHAT-BUG-1050745

First published: Thu Jan 09 2014(Updated: )

It was reported [1],[2] that when the fallback greeter is used in GDM3.x, if the disable-user-list setting is "true" (so a user list is not displayed, but entry fields for username and password), if a user enters their username and are then presented with a password prompt, if they were to click the "cancel" button then all of the user-interactive fields disappear. The user is then unable to login in or otherwise interact with the display manager, and must either kill X or reboot. There is no upstream fix as of yet. <a href="https://access.redhat.com/security/cve/CVE-2013-7273">CVE-2013-7273</a> was assigned [3] to this issue.
