Advisory ID: 16-0014
Publish Date: 2016-08-02
Multiple vulnerabilities have been identified in specific versions of ntpd identified above.
CVE-2016-1548 was issued in response to the discovery that an ntp client could be forced to change from basic
client/server mode to the interleaved symmetric mode. A remote attacker could use a spoofed packet that, when
processed by an ntp client, would cause that client to reject all future legitimate server responses, effectively
disabling time synchronization on that client.
CentOS has issued fixes for CVE-2016-1548 and the following related ntpd vulnerabilities.
MSL is based on the CentOS Linux distribution which is a stable, predictable, manageable and reproducible platform
derived from the sources of Red Hat Enterprise Linux (RHEL).
Additional CVEs may be applicable to other products - consult the product Security Bulletins and External Links section for more details.
MSL and other products have been confirmed to use affected ntpd versions.
