Description msiddiqu 2019-03-12 12:36:45 UTC
gio/gsocketclient.c in GNOME GLib 2.59.2 does not ensure that a parent GTask remains alive during the execution of a connection-attempting enumeration, which allows remote attackers to cause a denial of service (g_socket_client_connected_callback mishandling and application crash) via a crafted web site, as demonstrated by GNOME Web (aka Epiphany).
