This allows a malicious user to inject arbitrary code which may be executed by another user calling these libraries, with the privileges of the user calling these libraries. This problem has been fixed and sites are recommended to update relevant components as soon as possible. Details ======= A problem has been found with the EMI-2 dcache-srmclient, it contains world writable executable files. This allows a malicious user to inject arbitrary code which may be executed by another user calling these libraries, with the privileges of the user calling these libraries. As far as we can ascertain, it is not possible to inject code which may get executed as root, and the vulnerability is only exploitable by an authorized user. The User Interface (UI) and the Worker Nodes (WN) running EMI 2 or UMD 2 software contain this vulnerability. Sites are recommended to update relevant components as soon as possible. Risk category ============= This issue has been assessed as 'High' risk by the EGI SVG Risk Assessment Team. Affected software ================= dcache-srmclient-2.1.1-1 is the affected piece of software. Both the sl5 and sl6 versions in both EMI 2 and UMD 2 are affected. The issue is fixed in version dcache-srmclient-2.2.4-2.el5.x86_64.rpm Component installation information ================================== 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 should see: http://repository.egi.eu/category/umd_releases/distribution/umd-2/ Update UMD-2.2.2 Sites installing directly from EMI should see: http://www.eu-emi.eu/emi-2-matterhorn/updates/ (update 5) Recommendations =============== Sites who have installed EMI 2 or UMD 2 version of the dcache client are recommended to immediately update their software. Other information ================= Unfortunately, this problem was found after sites were asked to migrate to this software. Hence it has been fixed as an emergency release. The advisory made public at https://wiki.egi.eu/wiki/SVG:Advisory-SVG-2012-4600 after sites have had been given 1 week to update (by agreement with CSIRT) Credit ====== This vulnerability was reported by John Green.
