Free5gc v3.2.1 is vulnerable to Information disclosure.

In Free5gc v3.0.5, the AMF breaks due to malformed NAS messages.

An issue was discovered in free5GC version 3.3.0, allows remote attackers to execute arbitrary code and cause a denial of service (DoS) on AMF component via crafted NGAP message.

Buffer Overflow vulnerability in free5gc 3.3.0 allows attackers to cause a denial of service via crafted PFCP messages whose Sequence Number is mutated to overflow bytes.

Buffer Overflow vulnerability in free5gc 3.3.0, UPF 1.2.0, and SMF 1.2.0 allows attackers to cause a denial of service via crafted PFCP messages.

Buffer Overflow vulnerability in free5gc 3.3.0 allows attackers to cause a denial of service via crafted PFCP message with malformed PFCP Heartbeat message whose Recovery Time Stamp IE length is mutated to zero.

An issue in Free5gc v.3.3.0 allows a local attacker to cause a denial of service via the free5gc-compose component.

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.

In free5GC 3.2.1, a malformed NGAP message can crash the AMF and NGAP decoders via an index-out-of-range panic in aper.GetBitString.
