GNOME Display Manager (gdm) 3.4.1 and earlier, when disable-user-list is set to true, allows local users to cause a denial of service (unable to login) by pressing the cancel button after entering a user name.
A flaw was found in NetworkManager in versions before 1.30.0. Setting match.path and activating a profile crashes NetworkManager. The highest threat from this vulnerability is to system availability.
The GdkPixbufLoader function in GIMP ToolKit (GTK+) in GTK 2 (gtk2) before 2.4.13 allows context-dependent attackers to cause a denial of service (crash) via a malformed image file.
GDM 2.4.4.x before 2.4.4.4, and 2.4.1.x before 2.4.1.7, does not restrict the size of input, which allows attackers to cause a denial of service (memory consumption).
Linux distributions using CAP_SYS_NICE for gnome-shell may be exposed to a privilege escalation issue. An attacker, with low privilege permissions, may take advantage of the way CAP_SYS_NICE is currently implemented and eventually load code to increase its process scheduler priority leading to possible DoS of other services running in the same machine.
