openSUSE Security Update: Security update for ntp

Announcement ID: openSUSE-SU-2016:1636-1
Rating: important
References: #979302 #979981 #981422 #982056 #982064 #982065
#982066 #982067 #982068
Cross-References: CVE-2016-4953 CVE-2016-4954 CVE-2016-4955
CVE-2016-4956 CVE-2016-4957
Affected Products:
openSUSE Leap 42.1

An update that solves 5 vulnerabilities and has four fixes
is now available.


ntp was updated to version 4.2.8p8 to fix five security issues.

These security issues were fixed:
– CVE-2016-4953: Bad authentication demobilizes ephemeral associations
– CVE-2016-4954: Processing spoofed server packets (bsc#982066).
– CVE-2016-4955: Autokey association reset (bsc#982067).
– CVE-2016-4956: Broadcast interleave (bsc#982068).
– CVE-2016-4957: CRYPTO_NAK crash (bsc#982064).

These non-security issues were fixed:
– Keep the parent process alive until the daemon has finished
initialisation, to make sure that the PID file exists when the parent
– bsc#979302: Change the process name of the forking DNS worker process to
avoid the impression that ntpd is started twice.
– bsc#981422: Don’t ignore SIGCHILD because it breaks wait().
– bsc#979981: ntp-wait does not accept fractional seconds, so use 1
instead of 0.2 in ntp-wait.service.
– Separate the creation of ntp.keys and key #1 in it to avoid problems
when upgrading installations that have the file, but no key #1, which is
needed e.g. by “rcntp addserver”.

This update was imported from the SUSE:SLE-12-SP1:Update update project.
