    Libreswan is an implementation of IPsec and IKE for Linux. 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 such as virtual private network (VPN).

    The following packages have been upgraded to a later upstream version: libreswan (3.29). (BZ#1738853)

    Security Fix(es):

    * libreswan: vulnerability in the processing of IKEv1 informational packets due to missing integrity check     (CVE-2019-10155)
