"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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
