Some versions of dCache have a security vulnerability in the SRM subsystem.
We consider this to be a medium severity security problem and therefore you are strongly urged to upgrade.
If you are using the vdt-dcache package the upgrade from vdt-dcache 2.3.1 to 2.3.3 is available from the VDT dCache web site It contains dcache-server-1.9.2-10.noarch.rpm.
It is possible to upgrade just the SRM dcache node in order to activate the security patch.
The upgrade for 1.8.x version is not available because this version is no longer supported by dcache.
We encouraged everybody to upgrade dCache as soon as possible.
Please let us know if you have any questions or encounter any problems with upgrade.
