Language:

Synopsis

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

Description

The version of opensc installed on the remote host is prior to 0.19.0-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2323 advisory.

Potential PIN bypass.When the token/card was plugged into the computer and authenticated from one process, it could be used to provide cryptographic operations from different process when the empty, zero-length PIN and the token can track the login status using some of its internals. This is dangerous for OS logon/screen unlock and small tokens that are plugged permanently to the computer. (CVE-2023-40660)

multiple memory issues with pkcs15-init (enrollment tool) (CVE-2023-40661)

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

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

Solution

Run 'yum update opensc' to update your system.
