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).
The update package also includes non-security fixes. See advisory for details.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
