Synopsis

The remote openSUSE host is missing a security update.

Description

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'.

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

Solution

Update the affected ntp packages.
