Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201308-02
(D-Bus: Denial of Service)

using D-Bus which would cause _dbus_printf_string_upper_bound() to return
1024 bytes and crash, causing a Denial of Service condition.

Workaround :

There is no known workaround at this time.
