Synopsis

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

Description

The version of libksba installed on the remote host is prior to 1.3.5-1.10. It is, therefore, affected by a vulnerability as referenced in the ALAS-2022-1649 advisory.

 A vulnerability was found in the Libksba library due to an integer overflow within the CRL parser. The vulnerability can be exploited remotely for code execution on the target system by passing specially crafted data to the application, for example, a malicious S/MIME attachment. (CVE-2022-3515)

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 libksba' to update your system.
