Redhat wants to backport some security fixes we applied in 4.1 and 4.6 to the Solr tree to 3.6, because their user-base still uses this version. To help them with backporting across the major API/version changes, we should also do this on the 3.6 branch.
Redhat already assigned 3 CVE numbers to these issues and take the older issues seriously, and they will patch older versions and also force users to upgrade. cf, CVE-2013-6397 (
SOLR-4882), CVE-2013-6407 ( SOLR-3895), CVE-2013-6408 ( SOLR-4881).
To fully fix, we might need to backport more patches. I will take care of this. This issue may be useful, if we release a 3.6.3 package.
