Summary
A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password (OTP) key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a denial of service, degrading the availability of the IPA service.
