https://notcve.org/view.php?id=CVE-2016-10156
A flaw in systemd v228 in /src/basic/fs-util.c caused world writable suid files to be created when using the systemd timers features, allowing local attackers to escalate their privileges to root. This is fixed in v229. Un fallo en systemd v228 en /src/basic/fs-util.c causó que los archivos suid de escritura universal se crearan cuando se usan las características de los temporizadores systemd, permitiendo a atacantes locales escalar sus privilegios a root.

https://notcve.org/view.php?id=CVE-2016-7795
The manager_invoke_notify_message function in systemd 231 and earlier allows local users to cause a denial of service (assertion failure and PID 1 hang) via a zero-length message received over a notify socket. La función manager_invoke_notify_message en systemd 231 y versiones anteriores permite a usuarios locales provocar una denegación de servicio (fallo de afirmación y colgado de PID 1) a través de un mensaje de longitud cero recibido sobre una notificación de encaje. A flaw was found in the way systemd handled empty notification messages. A local attacker could use this flaw to make systemd freeze its execution, preventing further management of system services, system shutdown, or zombie process collection via systemd. • http://rhn.redhat.com/errata/RHSA-2016-2610.html http://rhn.redhat.com/errata/RHSA-2016-2694.html http://www.openwall.com/lists/oss-security/2016/09/28/9 http://www.openwall.com/lists/oss-security/2016/09/30/1 http://www.securityfocus.com/bid/93223 http://www.securitytracker.com/id/1037320 http://www.ubuntu.com/usn/USN-3094-1 https://github.com/systemd/systemd/issues/4234 https://www.agwa.name/blog/post/how_to_crash_systemd_in_one_tweet https:/ • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •

The manager_dispatch_notify_fd function in systemd allows local users to cause a denial of service (system hang) via a zero-length message received over a notify socket, which causes an error to be returned and the notification handler to be disabled. La función manager_dispatch_notify_fd en systemd permite a usuarios locales provocar una denegación de servicio (colgado de sistema) a través de un mensaje de longitud cero recibido sobre una notificación de encaje, lo que provoca que se devuelva un error y que el controlador de notificación se desactive.
