Amazon Linux AMI : openvpn (ALAS-2020-1410)

low Nessus Plugin ID 139090

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of openvpn installed on the remote host is prior to 2.4.9-1.23. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1410 advisory.

 This security issue is quite hard to abuse, requiring a fairly precise timing attack combined with guessing a just assigned peer-id reference. If successful, only a single client just initiating a new connection will experience a denial of service situation.(CVE-2020-11810)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update openvpn' to update your system.
