A vulnerability has been found in D-Bus which allows a local user to cause a Denial of Service.
|Package||sys-apps/dbus on all architectures|
|Affected versions||< 1.6.12|
|Unaffected versions||>= 1.6.12|
D-Bus is a message bus system which processes can use to talk to each other.
D-Bus’ _dbus_printf_string_upper_bound() function crashes if it returns exactly 1024 bytes.
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.
There is no known workaround at this time.
All D-Bus users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.6.12"
