"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by
multiple vulnerabilities as referenced in the SUSE-SU-2022:4586-1 advisory.

  - A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint
    checking. Note that this occurs after certificate chain signature verification and requires either a CA to
    have signed a malicious certificate or for an application to continue certificate verification despite
    failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a
    certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the
    stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this
    can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server
    requests client authentication and a malicious client connects. (CVE-2022-3786)

  - If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a
    write lock will be taken twice recursively. On some operating systems (most widely: Windows) this results
    in a denial of service when the affected process hangs. Policy processing being enabled on a publicly
    facing server is not considered to be a common setup. Policy processing is enabled by passing the
    `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()'
    function. Update (31 March 2023): The description of the policy processing enablement was corrected based
    on CVE-2023-0466. (CVE-2022-3996)

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