The remote host is missing an update for the 'systemd' package(s) announced via the referenced advisory. It fixes a zero-length message denial-of-service attack vulnerability, and includes non-security fixes for HMAC calculation, file descriptor acceptance, warning about missing install info, saving before starting [email protected], and database initialization

  - CVE-2016-7796: A zero-length message received over systemd's
  notification socket could make manager_dispatch_notify_fd() return an
  error and, as a side effect, disable the notification handler
  completely. As the notification socket is world-writable, this could
  have allowed a local user to perform a denial-of-service attack against
  systemd. (bsc#1001765)

  Additionally, the following non-security fixes are included:

  - Fix HMAC calculation when appending a data object to journal.
  (bsc#1000435)

  - Never accept file descriptors from file systems with mandatory locking
  enabled. (bsc#954374)

  - Do not warn about missing install info with 'preset'. (bsc#970293)

  - Save /run/systemd/users/UID before starting [email protected]. (bsc#996269)

  initialized. (bsc#982211)");
