| Description: | Summary:
The remote host is missing an update for the Huawei EulerOS 'ntp' package(s) announced via the EulerOS-SA-2016-1060 advisory.
Vulnerability Insight:
It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands.(CVE-2015-5194)
It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) was referenced by the statistics or filegen configuration command.(CVE-2015-5195)
It was found that NTP's :config command could be used to set the pidfile and driftfile paths without any restrictions. A remote attacker could use this flaw to overwrite a file on the file system with a file containing the pid of the ntpd process (immediately) or the current estimated drift of the system clock (in hourly intervals).(CVE-2015-5196)
It was discovered that the sntp utility could become unresponsive due to being caught in an infinite loop when processing a crafted NTP packet.(CVE-2015-5219)
It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntp_crypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially crafted NTP packet to crash ntpd.(CVE-2015-7691)
It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntp_crypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially crafted NTP packet to crash ntpd.(CVE-2015-7692)
A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd was configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory.(CVE-2015-7701)

An off-by-one flaw, leading to a buffer overflow, was found in cookedprint functionality of ntpq. A specially crafted NTP packet could potentially cause ntpq to crash.(CVE-2015-7852)
A flaw was found in the way NTP verified trusted keys during symmetric key authentication. An authenticated client (A) could use this flaw to modify a packet sent between a server (B) and a client (C) using a key that is ... [Please see the references for more information on the vulnerabilities]
