This has been fixed by the developers and a new version is available. This advisory is updated as some components required a re-release in order to fully resolve the problem. Details ======= The developers found a problem with the VOMS Java API where the CRL is not correctly checked. This means that if a VOMS server were to be compromised, and the appropriate server added to the CRL, VOMS certificates from this server may still be accepted. Although it is unlikely that a VOMs server were to be compromised, and this vulnerability is not exploitable by itself, serious problems would arise if a VOMS server were to be compromised and the CRL checking was not properly carried out. Hence this problem has been fixed. Risk category ============= This issue has been assessed as 'Moderate' risk by the EGI SVG Risk Assessment Team Affected software ================= All versions of the VOMS Java API up to and including version 2.0.8. This is fixed in VOMS version 2.0.10 as available in EMI 1 Update 23 and EMI 2 Update 8. The package has also been released in EGI UMD-1 Release 1.10.0 http://repository.egi.eu/2013/02/19/release-umd-1-10-0/ and UMD-2 Release 2.4.0 http://repository.egi.eu/2013/02/18/release-umd-2-4-0/ Additonally, in order to complete the elimination of this vulnerablity re-built components have been released as part of UMD-2 release 2.4.1 http://repository.egi.eu/2013/04/05/release-umd-2-4-1/ 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/ Sites installing directly from EMI should see: http://www.eu-emi.eu/emi-2-matterhorn/updates/ Recommendations =============== Sites are recommended to update relevant components to the VOMS java API 2.0.9 Credit ====== This vulnerability was reported by Andrea Ceccanti Timeline ======== Yyyy-mm-dd 2012-11-06 Vulnerability reported by Andrea Ceccanti stating that the VOMS team had found this problem and were fixing it 2012-11-07 Acknowledgement from the EGI SVG to the reporter 2012-11-20 Assessment by the EGI Software Vulnerability Group reported to the software providers 2013-01-28 Updated packages available in the EMI distribution 2013-02-19 Updated packages available in the EGI UMD distributions 2013-02-19 Public disclosure 2013-02-19 Removed from public web page as some components required re-build to fully resolve 2013-04-05 UMD 2.4.1 release made available which fully resolves the problem 2013-04-17 Public disclosure
