Upstream information

CVE-2018-12327 at MITRE

Description

Stack-based buffer overflow in ntpq and ntpdc of NTP version 4.2.8p11 allows an attacker to achieve code execution or escalate to higher privileges via a long string as the argument for an IPv4 or IPv6 command-line parameter. NOTE: It is unclear whether there are any common situations in which ntpq or ntpdc is used with a command line from an untrusted source.

Note from the SUSE Security Team

This problem affects only commandline tools and not the server. As these commandline tools are usually not run with attacker input we are considering this as moderate severity issue only. We currently do not plan to release LTSS updates.
