Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the libreswan package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- A traffic amplification flaw was found in the Internet Key Exchange version 1 (IKEv1) protocol. A remote attacker could use a libreswan server with IKEv1 enabled in a network traffic amplification denial of service attack against other hosts on the network by sending UDP packets with a spoofed source address to that server. (CVE-2016-5361)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libreswan package.
