openSUSE Security Update : ntp (openSUSE-2016-727)

high Nessus Plugin ID 91630

Synopsis

The remote openSUSE host is missing a security update.

Description

ntp was updated 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 :

- bsc#979302: Change the process name of the forking DNS worker process to avoid the impression that ntpd is started twice.

- bsc#979981: ntp-wait does not accept fractional seconds, so use 1 instead of 0.2 in ntp-wait.service.

- bsc#981422: Don't ignore SIGCHILD because it breaks wait().

- 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'.

Solution

Update the affected ntp packages.
