Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of nerdctl installed on the remote host is prior to 1.6.2-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2339 advisory.2024-02-01: CVE-2023-3978 was added to this advisory.
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-39325)
Text nodes not in the HTML namespace are incorrectly literally rendered, causing text which should be escaped to not be. This could lead to an XSS attack. (CVE-2023-3978)
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 nerdctl' to update your system.See Also
