Synopsis
The remote openSUSE host is missing a security update.Description
This update for systemd fixes the following security issue :- 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.

Additionally, the following non-security fixes are included :
- Fix HMAC calculation when appending a data object to journal. (bsc#1000435)
