Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2019-9633)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
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).
Remediation
Install update from vendor's website.
