The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2021:2392-1 advisory.

- The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic. (CVE-2021-34558)

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