Description
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).
Statement
This issue affects only the versions of glib2-2.59.1 and is fixed in version 2.59.2. The 2.59.1 was an unstable release and wasn't shipped with Red Hat Enterprise Linux 6, 7 and 8, hence Red Hat Enterprise Linux is not affected by this vulnerability.
