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.

GNOME Nautilus 42.2 allows a NULL pointer dereference and get_basename application crash via a pasted ZIP archive.

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).

GDM 2.4.4.x before 2.4.4.4, and 2.4.1.x before 2.4.1.7, does not limit the number or duration of commands and uses a blocking socket connection, which allows attackers to cause a denial of service (resource exhaustion) by sending commands and not reading the results.

When GNOME Dia before 2019-11-27 is launched with a filename argument that is not a valid codepoint in the current encoding, it enters an endless loop, thus endlessly writing text to stdout. If this launch is from a thumbnailer service, this output will usually be written to disk via the system's logging facility (potentially with elevated privileges), thus filling up the disk and eventually rendering the system unusable. (The filename can be for a nonexistent file.) NOTE: this does not affect an upstream release, but affects certain Linux distribution packages with version numbers such as 0.97.3.
