Advisories for Golang/Github.com/Free5gc/Udm package

An issue was discovered in Free5GC v4.0.0 and v4.0.1 allowing an attacker to cause a denial of service via the Nudm_SubscriberDataManagement API.

pkg/suci/suci.go in free5GC udm before 1.2.0, when Go before 1.19 is used, allows an Invalid Curve Attack because it may compute a shared secret via an uncompressed public key that has not been validated. An attacker can send arbitrary SUCIs to the UDM, which tries to decrypt them via both its private key and the attacker's public key.
