RHBA-2017:2576 - openssh bug fix update
Synopsis
openssh bug fix update
Type/Severity
Bug Fix Advisory None
Topic
Updated openssh packages that fix one bug are now available for Red Hat Enterprise Linux 7.
Description
OpenSSH is an SSH protocol implementation supported by a number of Linux, UNIX, and similar operating systems. It includes the core files necessary for both the OpenSSH client and server.
This update fixes the following bug:
- In Red Hat Enterprise Linux 7.4, the default value of the UseDNS configuration option had been changed to "No". This change prevented OpenSSH from translating IP addresses to host names to be used in server configuration files and access rules of the authorized_keys files. However, it also broke existing installations until manually corrected. With this update, the default value of UseDNS has been changed to "Yes", and the default configuration is compatible with Red Hat Enterprise Linux 7.3 and older installations again. (BZ#1479259)
Users of openssh are advised to upgrade to these updated packages, which fix this bug.
