Comment 1 David Walser 2020-05-12 16:52:28 CEST 
Updated packages uploaded by Stig-Ørjan.

Advisory:
========================

Updated libreswan packages fix security vulnerability:

An out-of-bounds buffer read flaw was found in the pluto daemon of libreswan.
An unauthenticated attacker could use this flaw to crash libreswan by sending
specially-crafted IKEv1 Informational Exchange packets. The daemon respawns
after the crash (CVE-2020-1763).
