This ntp update provides the following security and non security fixes :
Update to 4.2.8p4 to fix several security issues (bsc#951608) :
CVE-2015-7871: NAK to the Future: Symmetric association authentication bypass via crypto-NAK
CVE-2015-7855: decodenetnum() will ASSERT botch instead of returning FAIL on some bogus values
CVE-2015-7854: Password Length Memory Corruption Vulnerability
CVE-2015-7853: Invalid length data provided by a custom refclock driver could cause a buffer overflow
CVE-2015-7852 ntpq atoascii() Memory Corruption Vulnerability
CVE-2015-7851 saveconfig Directory Traversal Vulnerability
CVE-2015-7850 remote config logfile-keyfile
CVE-2015-7849 trusted key use-after-free
CVE-2015-7848 mode 7 loop counter underrun
CVE-2015-7701 Slow memory leak in CRYPTO_ASSOC
CVE-2015-7703 configuration directives ‘pidfile’ and ‘driftfile’ should only be allowed locally
CVE-2015-7704, CVE-2015-7705 Clients that receive a KoD should validate the origin timestamp field
CVE-2015-7691, CVE-2015-7692, CVE-2015-7702 Incomplete autokey data packet length checks
Use ntpq instead of deprecated ntpdc in start-ntpd (bnc#936327).
Add a controlkey to ntp.conf to make the above work.
Improve runtime configuration :
Read keytype from ntp.conf
Don’t write ntp keys to syslog.
Don’t let ‘keysdir’ lines in ntp.conf trigger the ‘keys’ parser.
Fix the comment regarding addserver in ntp.conf (bnc#910063).
Remove ntp.1.gz, it wasn’t installed anymore.
Remove ntp-4.2.7-rh-manpages.tar.gz and only keep ntptime.8.gz. The rest is partially irrelevant, partially redundant and potentially outdated (bsc#942587).
Remove ‘kod’ from the restrict line in ntp.conf (bsc#944300).
Use SHA1 instead of MD5 for symmetric keys (bsc#905885).
Require perl-Socket6 (bsc#942441).
Fix incomplete backporting of ‘rcntp ntptimemset’.
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.
