The CVE-2017-15135 issue was discovered by Martin Poole (Red Hat).

Bug Fix(es) :

* Previously, if an administrator configured an index for an attribute with a specific matching rule in the 'nsMatchingRule' parameter, Directory Server did not use the retrieved indexer. As a consequence, Directory Server did not index the values of this attribute with the specified matching rules, and searches with extended filters were unindexed. With this update, Directory Server uses the retrieved indexer that processes the specified matching rule. As a result, searches using extended filters with a specified matching rule are now indexed. (BZ#1536343)

Solution

Update the affected packages.
