openSUSE Security Update : systemd (openSUSE-2016-1194)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


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.
(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)

- Make sure that /var/lib/systemd/sysv-convert/database is
always initialized. (bsc#982211)

- Remove daylight saving time handling and tzfile parser.
(bsc#990074)

- Make sure directory watch is started before cryptsetup.
(bsc#987173)

- Introduce sd_pid_notify() and sd_pid_notifyf() APIs.
(bsc#987857)

- Set KillMode=mixed for our daemons that fork worker
processes.

- Add nosuid and nodev options to tmp.mount.

- Don't start console-getty.service when /dev/console is
missing. (bsc#982251)

- Correct segmentation fault in udev/path_id due to
missing NULL check. (bsc#982210)
