Libreswan 3.22 < 4.15 / 5.0rc1 < 5.0 DoS

high Nessus Plugin ID 193875

Synopsis

The version of Libreswan installed on the remote host is affected by a denial of service vulnerability.

Description

The version of Libreswan installed on the remote host is between 3.22 and 4.14, or a 5.0 release candidate prior to 5.0 . It is, therefore, affected by a denial of service (DoS) vulnerability. The Libreswan Project was notified of an issue causing libreswan to restart when using IKEv1 without specifying an esp= line. When the peer requests AES-GMAC, libreswan's default proposal handler causes an assertion failure and crashes and restarts. IKEv2 connections are not affected.

Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Libreswan version 4.15, 5.0 or later.
