Affected Products:

______________________________________________________________________________

 

An update that solves one vulnerability and has 5 fixes is

now available.

 

Description:

 

This update for systemd fixes the following issues:

 

- 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 user ( -at -) .service. (bsc#996269)

- Make sure that /var/lib/systemd/sysv-convert/database is always

initialized. (bsc#982211)
