ipa: memory corruption when using get_user_grouplist()
The get_user_grouplist function in the extdom plug-in in FreeIPA before 4.1.4 does not properly reallocate memory when processing user accounts, which allows remote attackers to cause a denial of service (crash) via a group list request for a user that belongs to a large number of groups.
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 slapi-nis: infinite loop in getgrnam_r() and getgrgid_r()
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.
