Multiple Vulnerabilities in ntpd versions < 4.2.8p8 / < 4.3.93

Advisory ID: 16-0014
Publish Date: 2016-08-02
Revision: 1.0

Summary

Multiple vulnerabilities have been identified in specific versions of ntpd identified above.

Detailed Description

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.

CVE-2016-7979
CVE-2016-1547
CVE-2016-1548
CVE-2016-2106
CVE-2016-1550
CVE-2016-2518

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).
