Fedora 34: FEDORA-2021-f93243d461 Critical: slapi-nis DoS Issue

This package provides two plugins for Red Hat and 389 Directory Server.

The NIS Server plugin allows the directory server to act as a NIS server

for clients, dynamically generating and updating NIS maps according to

its configuration and the contents of the DIT, and serving the results to

clients using the NIS protocol as if it were an ordinary NIS server.

The Schema Compatibility plugin allows the directory server to provide an

alternate view of entries stored in part of the DIT, optionally adding,

dropping, or renaming attribute values, and optionally retrieving values

for attributes from multiple entries in the tree.
