Security update for ntp
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().
- 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'.

Описание
ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time.

Описание
The process_packet function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (peer-variable modification) by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication.

Описание
ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service (peer-variable clearing and association outage) by sending (1) a spoofed crypto-NAK packet or (2) a packet with an incorrect MAC value at a certain time.

Описание
ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (interleaved-mode transition and time change) via a spoofed broadcast packet. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-1548.
