Descriptions

The dbus-daemon in D-Bus before 1.6.24 and 1.8.x before 1.8.8 does not properly close old connections, which allows local users to cause a denial of service (incomplete connection consumption and prevention of new connections) via a large number of incomplete connections.

El demonio de dbus en D-Bus anterior a 1.6.24 y 1.8.x anterior a 1.8.8 no cierra debidamente conexiones antiguas, lo que permite a usuarios locales causar una denegación de servicio (conexiones consumo incompleto y prevención de nuevas conexiones) a través de un gran número de conexiones incompletas.

Simon McVittie discovered that DBus incorrectly handled the file descriptors message limit. A local attacker could use this issue to cause DBus to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Alban Crequy discovered that DBus incorrectly handled a large number of file descriptor messages. A local attacker could use this issue to cause DBus to stop responding, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Various other issues were also addressed.
