CVE-2019-9633 (CCN-158171)

Assigned:2019-01-14
Published:2019-01-14
Updated:2021-07-21
Summary: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).
