CVE-2014-0979

Publication date 23 January 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The start_authentication function in lightdm-gtk-greeter.c in LightDM GTK+ Greeter before 1.7.1 does not properly handle the return value from the lightdm_greeter_get_authentication_user function, which allows local users to cause a denial of service (NULL pointer dereference) via an empty username.
