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
(bsc#982065).
- 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
returns.
- 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".
