ARC 15.03 update 12
Description
The Advanced Resource Connector (ARC) middleware is an Open Source software solution to enable distributed computing infrastructures with the emphasis on processing large volumes of data. ARC provides an abstraction layer over computational resources, complete with input and output data movement functionalities. The security model of ARC is identical to that of Grid solutions, relying on delegation of user credentials and the concept of Virtual Organisations. ARC also provides client tools, as well as API in C++, Python and Java.
Release notes
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.
NorduGrid ARC 15.03 has received an update to:
- core, clients, CE, Infosys and gridftp - from version 5.2.1 to 5.2.2
- documents - from 2.0.12 to 2.0.13
Nagios plugins, CAnL C++ and metapackages are unchanged.
See the release notes for details.
