CVE-2022-23094 (GCVE-0-2022-23094)

Vulnerability from cvelistv5 – Published: 2022-01-15 01:37 – Updated: 2024-08-03 03:28

Summary

Libreswan 4.2 through 4.5 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted IKEv1 packet because pluto/ikev1.c wrongly expects that a state object exists. This is fixed in 4.6.
