The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename. (CVE-2015-7976)
Impact
A remote user who uses the ntpq saveconfig command may exploit this flaw to create a file name with special characters when querying the NTP server.
