FYI -------- Forwarded Message -------- Subject: [Noc-managers] EGI SVG Advisory 'High' RISK - Vulnerability in the dCache SRM server module [EGI-SVG-2015-9495] Date: Tue, 22 Sep 2015 13:15:25 +0000 From: linda.cornwall at stfc.ac.uk To: site-security-contacts at mailman.egi.eu, ngi-security-contacts at mailman.egi.eu, csirt at mailman.egi.eu, noc-managers at mailman.egi.eu CC: svg-rat at mailman.egi.eu ** AMBER information - Limited distribution ** ** see https://wiki.egi.eu/wiki/EGI_CSIRT:TLP for distribution restrictions ** EGI SVG ADVISORY [EGI-SVG-2015-9495] Title: EGI SVG Advisory 'High' RISK - Vulnerability in the dCache SRM server module [EGI-SVG-2015-9495] Date: 2015-09-22 Updated: This advisory will be placed on the wiki after the patch has been available in all distributions for at least 2 weeks. URL: https://wiki.egi.eu/wiki/SVG:Advisory-SVG-2015-9495 Introduction ============ dCache [R 1] is a data storage and retrieval system. A vulnerability has been found in the dCache SRM server module by the dCache team, who also alerted SVG to this problem. A fixed binary version is available on the dCache site [R 2]. A fixed version is not yet available in the EGI UMD. Details ======= See the dCache page. [R 1] Risk category ============= This issue has been assessed as 'High' risk by the EGI SVG Risk Assessment Team. Affected software ================= All dCache versions prior to this patch are affected. The releases which fix this issue are are: 2.13.9 2.12.21 2.11.32 2.10.41 2.6.52 It was noted by the dCache team that several site still run the unsupported 2.6 dCache. Given these sites currently suffer from a High risk vulnerability, dCache have made an additional release: 2.6.52 Mitigation ========== N/A. Component installation information ================================== Updates are available on the dCache site [R 2] Note that at present the patch is only available from the dCache site. Release notes are available at https://www.dcache.org/downloads/1.9/release-notes-2.13.shtml https://www.dcache.org/downloads/1.9/release-notes-2.12.shtml https://www.dcache.org/downloads/1.9/release-notes-2.11.shtml https://www.dcache.org/downloads/1.9/release-notes-2.10.shtml https://www.dcache.org/downloads/1.9/unsupported/release-notes-2.6.shtml The official repository for the distribution of grid middleware for EGI sites is repository.egi.eu which contains the EGI Unified Middleware Distribution (UMD). Sites using the EGI UMD 3 should see: http://repository.egi.eu/category/umd_releases/distribution/umd-3/ Other Information ================== To give sites time to upgrade their dCache, the dCache team will not release any details of the vulnerability at this time. This includes not making public the source-code for the fix for a 'grace period' of two weeks, as doing so would also reveal information on the vulnerability. During this two week grace period, dCache will make no further releases. Once the grace-period elapses, all code changes will be pushed into github and dCache will continue normal bug-fix release cycles. The SVG hopes that this software can be made available in the UMD before dCache reveals the change to the source code. Recommendations =============== Sites are recommended to update the SRM head node component as soon as possible. Sites installing from the EGI UMD may wait until the patch is available in the EGI UMD if they wish. Credit ====== This vulnerability was discovered by Gerd Behrmann (NDGF) from the dCache team.
