		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">libreswan security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for libreswan is now available for openEuler-22.03-LTS.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Libreswan is an implementation of IKEv1 and IKEv2 for IPsec. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services.  These services allow you to build secure tunnels through untrusted networks.  Everything passing through the untrusted net is encrypted by the ipsec gateway machine and decrypted by the gateway at the other end of the tunnel.  The resulting tunnel is a virtual private network or VPN. This package contains the daemons and userland tools for setting up Libreswan. Libreswan also supports IKEv2 (RFC7296) and Secure Labeling Libreswan is based on Openswan-2.6.38 which in turn is based on FreeS/WAN-2.04

Security Fix(es):

Libreswan 4.9 allows remote attackers to cause a denial of service (assert failure and daemon restart) via crafted TS payload with an incorrect selector length.(CVE-2023-23009)</Note>
