The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6672-1 advisory.

  - A cryptographic vulnerability exists in Node.js <19.2.0, <18.14.1, <16.19.1, <14.21.3 that in some cases     did does not clear the OpenSSL error stack after operations that may set it. This may lead to false     positive errors during subsequent cryptographic operations that happen to be on the same thread. This in     turn could be used to cause a denial of service. (CVE-2023-23919)

  - An untrusted search path vulnerability exists in Node.js. <19.6.1, <18.14.1, <16.19.1, and <14.21.3 that     could allow an attacker to search and potentially load ICU data when running with elevated privileges.
    (CVE-2023-23920)

  - Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be     very slow. Impact summary: Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL     subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience notable to     very long delays when processing those messages, which may lead to a Denial of Service. An OBJECT     IDENTIFIER is composed of a series of numbers - sub-identifiers - most of which have no size limit.
    OBJ_obj2txt() may be used to translate an ASN.1 OBJECT IDENTIFIER given in DER encoding form (using the     OpenSSL type ASN1_OBJECT) to its canonical numeric text form, which are the sub-identifiers of the OBJECT     IDENTIFIER in decimal form, separated by periods. When one of the sub-identifiers in the OBJECT IDENTIFIER     is very large (these are sizes that are seen as absurdly large, taking up tens or hundreds of KiBs), the     translation to a decimal number in text may take a very long time. The time complexity is O(n^2) with 'n'     being the size of the sub-identifiers in bytes (*). With OpenSSL 3.0, support to fetch cryptographic     algorithms using names / identifiers in string form was introduced. This includes using OBJECT IDENTIFIERs     in canonical numeric text form as identifiers for fetching algorithms. Such OBJECT IDENTIFIERs may be     received through the ASN.1 structure AlgorithmIdentifier, which is commonly used in multiple protocols to     specify what cryptographic algorithm should be used to sign or verify, encrypt or decrypt, or digest     passed data. Applications that call OBJ_obj2txt() directly with untrusted data are affected, with any     version of OpenSSL. If the use is for the mere purpose of display, the severity is considered low. In     OpenSSL 3.0 and newer, this affects the subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS. It also impacts     anything that processes X.509 certificates, including simple things like verifying its signature. The     impact on TLS is relatively low, because all versions of OpenSSL have a 100KiB limit on the peer's     certificate chain. Additionally, this only impacts clients, or servers that have explicitly enabled client     authentication. In OpenSSL 1.1.1 and 1.0.2, this only affects displaying diverse objects, such as X.509     certificates. This is assumed to not happen in such a way that it would cause a Denial of Service, so     these versions are considered not affected by this issue in such a way that it would be cause for concern,     and the severity is therefore considered low. (CVE-2023-2650)

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