Description

A flaw was found in libtirpc. An authenticated remote attacker could exploit this vulnerability by sending oversized wrapped data requests to an RPC (Remote Procedure Call) service configured with RPCSEC_GSS (Remote Procedure Call Security-Generic Security Service) integrity or privacy. This can lead to unbounded memory allocation, resulting in a Denial of Service (DoS) by exhausting system resources and causing the service to become unstable or terminate.
