high Nessus Plugin ID 142984

Language:

Synopsis

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

Description

The version of curl installed on the remote host is prior to 7.61.1-12.95. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1444 advisory.

 A flaw was found in libcurl from versions 7.29.0 through 7.71.1. An application that performs multiple requests with libcurl's multi API, and sets the `CURLOPT_CONNECT_ONLY` option, might experience libcurl using the wrong connection. The highest threat from this vulnerability is to data confidentiality.
 (CVE-2020-8231)

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 curl' to update your system.
