The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Nimble is a package manager for the Nim programming language. In Nim release versions before versions     1.2.10 and 1.4.4, nimble refresh fetches a list of Nimble packages over HTTPS without full verification     of the SSL/TLS certificate due to the default setting of httpClient. An attacker able to perform MitM can     deliver a modified package list containing malicious software packages. If the packages are installed and     used the attack escalates to untrusted code execution. (CVE-2021-21374)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:10101-1 advisory.

    Includes upstream security fixes for:

    * (boo#1175333, CVE-2020-15693) httpClient is vulnerable to a       CR-LF injection
    * (boo#1175334, CVE-2020-15692) mishandle of argument to       browsers.openDefaultBrowser
    * (boo#1175332, CVE-2020-15694) httpClient.get().contentLength()       fails to properly validate the server response
    * (boo#1192712, CVE-2021-41259) null byte accepted in getContent       function, leading to URI validation bypass
    * (boo#1185948, CVE-2021-29495) stdlib httpClient does not       validate peer certificates by default
    * (boo#1185085, CVE-2021-21374) Improper verification of the       SSL/TLS certificate
    * (boo#1185084, CVE-2021-21373) 'nimble refresh' falls back to a       non-TLS URL in case of error
    * (boo#1185083, CVE-2021-21372) doCmd can be leveraged to execute       arbitrary commands
    * (boo#1181705, CVE-2020-15690) Standard library asyncftpclient       lacks a check for newline character

    Update to 1.6.6

    * standard library use consistent styles for variable names so it       can be used in projects which force a consistent style with
      --styleCheck:usages option.
    * ARC/ORC are now considerably faster at method dispatching,       bringing its performance back on the level of the refc memory       management.
