Release Notes for NorduGrid ARC 15.03 update 12

February 7, 2017

This is a bugfix release, addressing a vulnerability discovered in 15.03u11.

The vulnerability is related to the performance logging feature, specifically to the folder /var/log/arc/perfdata and its given permissions. The issue is not considered severe, but additional protective measures have anyway been introduced. From version 15.03u12 the folder in mention will only be created if the system administrator explicitly asks for it.

The performance logging feature is off by default, both in this and earlier versions of ARC. In this version, in addition the folder will only be created if the feature is turned on.

If you want to enable the performance logging for debugging purposes or other specific reasons, this is as before done in your configuration settings. The flag to turn on the performance logging has changed from "yes" to "expert-debug-on", see documentation.
