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.

Security readout for executives and security teams

This is a remote availability bug in FreeIPA’s extdom plugin. A group-list request for a user with many group memberships can crash affected FreeIPA servers. The described impact is identity service disruption, not data theft or privilege gain. Exposure is most likely on FreeIPA deployments older than 4.1.4 where the extdom plug-in is enabled or reachable. Environments with users in very large numbers of groups are the specific trigger condition described. Prioritize remediation for production identity systems because outages can disrupt authentication-dependent business services. Urgency is lower than code execution issues, but aging FreeIPA instances should be patched or retired. Mitigation focus: Upgrade FreeIPA to 4.1.4 or vendor-supported fixed packages.; Review Red Hat and Fedora advisories for applicable package versions.; Limit reachability to FreeIPA services where operationally feasible..
