CVE-2014-7271 [HIGH] CVE-2014-7271 sddm: user "sddm" can login without authentication.
CVE-2014-7271 sddm: user "sddm" can login without authentication.
It was reported that it's possible to login as "sddm" user without authentication:
This is since if sddm detects that user in the PamBackend,
it has:
if (user == "sddm")
service = "sddm-greeter";
else if (m_app->session()->path().isEmpty())
service = "sddm-check";
else if (m_autologin)
service = "sddm-autologin";
result = m_pam->start(service, user);
and the sddm-greeter PAM config basically just has a pam_permit.
More info is available at [1]. Upstream patch is at [2].
