Fedora 21: slapi-nis Security Update
Summary
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.
Update Information:
CVE-2015-1827: It was discovered that the IPA extdom Directory Server plug-in did not correctly perform memory reallocation when handling user account information. A request for a list of groups for a user that belongs to a large number of groups would cause a Directory Server to crash.
CVE-2015-0283: It was discovered that the slapi-nis Directory Server plug-in did not correctly perform memory reallocation when handling user account information. A request for information about a group with many members, or a request for a user that belongs to a large number of groups, would cause a Directory Server to enter an infinite loop and consume an excessive amount of CPU time.
These issues were discovered by Sumit Bose of Red Hat.
