libreswan-3.20-5.0.1.el7.AXS7

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).

This update fixes the following bugs:

* Previously, when a connection that uses the Extended Authentication (XAUTH) client and a server scheme without the IPSec Mode-configuration (ModeCFG) was established, the server expected a client reply message that never came because the server did not send a request. As a consequence, the connection was deleted within a minute. With this update, support for XAUTH username/password scheme that does not use ModeCFG for IP assignment has been added, and connections no longer terminate unexpectedly in the described scenario. (BZ#1501809)

* In Asianux Server 7.4, the Libreswan XAUTH password length became limited to 63 characters a null-terminated character. Consequently, users with longer passwords could not successfully authenticate using the password prompt. This update adds support for passwords longer than 64 characters, and users can now authenticate with a password containing up to 127 characters. (BZ#1503949)

Users of libreswan are advised to upgrade to these updated packages, which fix these bugs.
