| Description: | Summary:
The remote host is missing an update for the 'ntp' package(s) announced via the SUSE-SU-2015:2058-1 advisory.
Vulnerability Insight:
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potentially outdated (bsc#942587).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'.

'ntp' package(s) on SUSE Linux Enterprise Desktop 11-SP4, SUSE Linux Enterprise Server 11-SP4, SUSE Linux Enterprise Server for SAP Applications 11-SP4.
