The version of openssl installed on the remote host is prior to 1.0.2k-19. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1721 advisory.

    It was found that openssl assumed ASN.1 strings to be NUL terminated. A malicious actor may be able to     force an application into calling openssl function with a specially crafted, non-NUL terminated string to     deliberately hit this bug, which may result in a crash of the application, causing a Denial of Service     attack, or possibly, memory disclosure. The highest threat from this vulnerability is to data     confidentiality and system availability. (CVE-2021-3712)

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.
