This has neem resolved some time ago. Risk category ============= This issue has been assessed as 'Moderate' risk by the EGI SVG Risk Assessment Team. Affected software ================= This is fixed in glite-wms-interface-3.6.2-1 which was released as part of WMS 3.6.2. Earliest fixed version in the UMD likely to be WMS 3.6.3 released in April 2014. All versions of glite-wms-wmproxy-dirmanager prior to this are likely to be affected.
