Identify and remediate systems affected by this advisory.
Topic
Updated chrony packages that fix one bug are now available for Red Hat Enterprise Linux 6.
Description
The chrony suite, chronyd and chronyc, is an advanced implementation of the Network Time Protocol (NTP), specially designed to support systems with intermittent connections. It can synchronize the system clock with NTP servers, hardware reference clocks, and manual input. It can also operate as an NTPv4 (RFC 5905) server or peer to provide a time service to other computers in the network.
This update fixes the following bug:
- When chronyd was configured with the smoothtime directive and the leaponly option to perform a server leap smear, the direction of smoothing could be determined incorrectly due to numerical errors in floating point operations. This consequently caused an assertion failure and chronyd terminated unexpectedly. A patch has been applied, which ensures that the direction is calculated and applied correctly when small offsets are employed in a time update. (BZ#1401533)
Users of chrony are advised to upgrade to these updated packages.
