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. **UPDATE** A fixed version is now available in the EGI UMD **UPDATE 2015-10-26 ** The advisory is public, the fix has been in the UMD for over 3 weeks, so info on details of the vulnerability may become public. Recommendations =============== Sites are recommended to update the SRM head node component as soon as possible if they have not done so already.
