Affected software and risk
==========================
Package : globus-url-copy, uberftp, globus-gridftp-server
CVE ID : N/A
Applications and sites should be aware that requesting data-channel encryption (i.e. PROT E) when using gridftp is no guarantee that this will actually be enabled.
This affects (at least) globus-url-copy and uberftp. Third-party transfers using a globus-gridftp-server are also affected, which includes DPM.
This is considered 'Low' risk to the EGI infrastructure as a whole, but applications should be aware not to rely on data-channel encryption.
Actions required/recommended
============================
Anyone relying on encrypted transfers using gridftp should not rely on gridftp's data-channel encryption but instead encrypt data before transmission.
If anyone becomes aware of any situation where this vulnerability has a significant impact on the EGI infrastructure or any usage in EGI then please inform EGI SVG.
More information
================
Not all gridftp servers implement data-channel authentication (DCAU).
In case DCAU is not available, a number of gridftp tools also do not support data-channel encryption (PROT E).
These tools then silently fail-over to data protection level clear (PROT C).
Currently, dCache does not support DCAU, hence clients to dCache typically cannot use data-channel encryption.
For globus-url-copy, PROT E is requested using the -dcpriv commandline flag, for uberftp it is requested using the "prot E" command.
In case a third-party transfer is done from a globus-gridftp-server, the same silent failover occurs.
See [R 1] for the originally reported issue.
Note that the Globus Toolkit is no longer maintained by the Globus team, except for security patches, see [R 2]
However the Grid Community Forum [R 3] has produced an (open source) fork of the Globus toolkit, called the Grid Community Toolkit (GCT).
The GCT packages will also replace the current globus-toolkit packages in EPEL and Debian but will be binary compatible.
The GCT may release an updated version of the globus-url-copy and globus-gridftp-server to partially address this issue, but due to the variety of tools involved, a full fix is not possible.

1) NGIs argus servers configuration
The ARGUS version that fixes the PAP permissions has been released in UMD 4.6: http://repository.egi.eu/2017/12/18/release-umd-4-6-0/
It is important updating to this version.
Moreover, as reported by EGI-CSIRT during the February OMB, several NGI ARGUS servers are not properly configured and they are not passing the nagios tests (eu.egi.Argus-DNs probe):
https://argo-mon.egi.eu/nagios/cgi-bin/status.cgi?servicegroup=SERVICE_ngi.…
Tickets have been opened against the affected sites.
How the probe works:
- Central Argus server suspend 1 fake DN each day
- Argo looks for this DN in NGI Arguses
Requirements for passing the test:
- NGI Argus must be configured to fetch DNs
- Argo must be able to connect to NGI Argus
- Argo DN must be authorized to query DNs
Information about the nagios errors and possible solutions: https://wiki.egi.eu/wiki/EGI_CSIRT:Central_emergency_suspension#NGI_Argus_M…
Information on global banning set-up: https://wiki.nikhef.nl/grid/Argus_Global_Banning_Setup_Overview#NGI_Argus
2) WMS servers decommission and related nagios probe
In order to follow-up the WMS servers decommission, it has been deployed a specific nagios probes detecting the WMS servers still in production, eu.egi.sec.WMS:
https://wiki.egi.eu/wiki/MW_SAM_tests#General_tests
Starting from March, the probe is returning a CRITICAL status for the detected WMS instances, and the ROD teams are opening a ticket to the sites that haven't finished the decommission process yet:
please report in the ticket the timeline for dismissing your WMS servers, in according to https://wiki.egi.eu/wiki/PROC12 .
Detected servers: https://argo-mon.egi.eu/nagios/cgi-bin/status.cgi?servicegroup=SERVICE_WMS&…
3) UMD3 shutdown
The UMD3 distribution is DEPRECATED. Sites are kindly asked to switch from UMD3/SL6 to UMD4/SL6 repositories: this can be easily done upgrading to the UMD4/SL6 version of the umd-release, and updating the list of the packages.
The proposed deadline to shutdown the UMD3 repository is April 30th; after that, the UMD3 repository will be no longer available.
To perform the repository upgrade, please refer to http://repository.egi.eu/category/umd_releases/distribution/umd-4/
For each single product, please carefully check the official product-specific documentation and the release notes provided by the Technology Provider. Especially, please take care that during the switch you can jump to new major versions; hence it is always very important to CAREFULLY READ UPGRADE GUIDELINES AND RELEASE NOTES of the products you are updating.
For any issue with the switch, please opena a GGUS ticket to the EGI Software Provisioning Support Unit.
4) UMD 4.6.1
UMD 4.6.1 is a fix release, containing the following product updates, both for CentOS7 and SL6. Please find details at http://repository.egi.eu/category/umd_releases/distribution/umd-4/ and the updated product overview at https://wiki.egi.eu/wiki/UMD_products
APEL-SSM 2.2.0 - Added a check that certificates have not expired before starting SSM. SSL errors now propagated out properly and saved for received messages. Trimmed down the number of log messages generated for receivers. Added python-devel build requirement for non fedora-packager OSs (CentOS)
DPM 1.9.2 - This update includes releases 1.9.2 and lcgdm 0.19.0. It contains a fix for dpm-listspaces wrongly reporting 0 free space for pools See http://lcgdm.web.cern.ch/dpm-192-release
XRootD 4.7.1 - various bug fixes https://github.com/xrootd/xrootd/blob/v4.7.1/docs/ReleaseNotes.txt

The CA-MCGILL-CLUMEQ-T2 site needs to be decommissioned by the end of January 2018 since new equipment for a new site will be brought in to the same space where the current one is. This then, is to advise all VOs we support that we will declare an indefinite downtime on the CEs in order to drain the jobs sent to the site. The SE will be put offline by end of the month January, time when all data is expected to have been migrated to other Canadian sites. There are new sites in ROC_Canada to take up the activities of the CA-MCGILL-CLUMEQ-T2 thus maintaining the required pledge to the WLCG.

Dear EGI users,
as previously announced, in January 2018 it is going to start the decommission procedure for all the WMS servers in the infrastructure: they will be put in draining in order to avoid submissions of new jobs and to allow the ending of the ones already submitted.
As alternative workload management system, EGI can provide support for migrating to the DIRAC service, a tool that provides features very similar to the WMS ones.
A central server (DIRAC4EGI) is available for the EGI user communities: if you need a Workload Management System for your daily activities, please discuss it with your VO managers and get in contact with EGI Operations through a GGUS ticket. Together the DIRAC supporters, we can set-up the server for your VO and provide support for the migration.
It is also available a quick "How to" for accessing to DIRAC4EGI and using it by CLI: https://wiki.egi.eu/wiki/HOWTO22
In the HowTO you can find links to the general DIRAC guides as well.
Should you have any question, do not hesitate to contact your VO/NGI managers and EGI Operations.
Best regards,
EGI Operations

This is the first alert sent by SVG to the VO managers (VM image endorsers) and VO security contacts via the broadcast tool.
Affected software and risk
==========================
Vulnerabilities have been reported concerning Tomcat remote execution in non-standard configurations.
Package : Tomcat
CVE ID : CVE-2017-12615, CVE-2017-12617
Remote execution vulnerabilities have been reported concerning Tomcat, however in most configurations they are unlikely to be exploitable. [R 1] [R 2] [R 3] [R 4]
If any site or Virtual Appliance (VM image) endorser is aware that any of these or other tomcat vulnerabilities presents a serious problem to EGI, please inform the EGI SVG.
This alert is being sent to the VO managers and VO security contacts via the EGI broadcast tool, as well as the usual contacts.
Actions required/recommended
============================
For Grid sites, no action is necessary.
There is the possibility that for some FedCloud applications/Virtual Machines (VMs) using Tomcat, that insecure configurations may exist, although SVG is not aware of any. If any site or Virtual Appliance (VM image) endorser is aware that any of these or other tomcat vulnerabilities presents a serious problem to EGI, please inform the EGI SVG.
Affected software details
=========================
Various versions of tomcat are vulnerable - See [R 3] - [R 9]
More information
================
If "readonly" is set to 'TRUE' which is the default in RedHat, these vulnerabilities are not exploitable. EGI Grid Middleware using tomcat has been checked by SVG members, and no exploitable usage of tomcat has been found.
It is possible that exploitable configurations exist in the EGI Federated Cloud.
Anyone developing FedCloud Virtual Appliances (VM images) which use tomcat should check that they are not vulnerable and if they are take appropriate action and inform EGI SVG.
