Amazon Linux 2 : ca-certificates (ALAS-2021-1710)

high Nessus Plugin ID 153883

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of ca-certificates installed on the remote host is prior to 2021.2.50-72. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1710 advisory.

- Update of ca-certificates to version 2021.2.50-72.amzn2.0.1 addresses the expiring IdentTrust DST Root CA X3, which affected some Let's Encrypt TLS certificates. The effect of the expiring certificate would be an inability of OpenSSL to validate impacted certificates issued by Let's Encrypt. Impacted customers may have experienced connection or certificate errors when attempting to connect to certain websites or APIs that use Let's Encrypt certificates. (ALAS2-2021-1710)

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 ca-certificates' to update your system.
