March 31, 2015
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
Summary
IPA is an integrated solution to provide centrally managed Identity (machine,
user, virtual machines, groups, authentication credentials), Policy
(configuration settings, access control information) and Audit (events,
logs, analysis thereof).
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.
