<p>D-Bus is a message bus system which processes can use to talk to each
<p>D-Bus’ _dbus_printf_string_upper_bound() function crashes if it
returns exactly 1024 bytes.
<impact type="normal">
<p>A local attacker could provide specially-crafted input to an application
using D-Bus which would cause _dbus_printf_string_upper_bound() to return
1024 bytes and crash, causing a Denial of Service condition.
<p>There is no known workaround at this time.</p>
<p>All D-Bus users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=sys-apps/dbus-1.6.12"
