CVSS: 6.8EPSS: 0%CPEs: 13EXPL: 2CVE-2016-7796 – systemd: freeze when PID 1 receives a zero-length message over notify socket
https://notcve.org/view.php?id=CVE-2016-7796
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. 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://lists.opensuse.org/opensuse-security-announce/2016-10/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00016.html http://rhn.redhat.com/errata/RHSA-2017-0003.html http://www.openwall.com/lists/oss-security/2016/09/30/1 http://www.securityfocus.com/bid/93250 http://www.securitytracker.com/id/1037320 https://bugzilla.redhat.com/show_bug.cgi?id=1381911 https://github.com/systemd/systemd/issues/4234#issuecomment-250441246 https://rhn.redhat.com/e • CWE-20: Improper Input Validation CWE-253: Incorrect Check of Function Return Value •
