NVD Description

Note: Versions mentioned in the description apply only to the upstream ipa-client-samba package and not the ipa-client-samba package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the /ipa/migration/migration.py endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service.
