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) (CVE-2023-40660, CVE-2023-40661)

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.
