"The remote host is affected by the vulnerability described in GLSA-202403-03 (UltraJSON: Multiple Vulnerabilities)

  - UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Affected
    versions were found to improperly decode certain characters. JSON strings that contain escaped surrogate
    characters not part of a proper surrogate pair were decoded incorrectly. Besides corrupting strings, this
    allowed for potential key confusion and value overwriting in dictionaries. All users parsing JSON from
    untrusted sources are vulnerable. From version 5.4.0, UltraJSON decodes lone surrogates in the same way as
    the standard library's `json` module does, preserving them in the parsed output. Users are advised to
    upgrade. There are no known workarounds for this issue. (CVE-2022-31116)

  - UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. In versions
    prior to 5.4.0 an error occurring while reallocating a buffer for string decoding can cause the buffer to
    get freed twice. Due to how UltraJSON uses the internal decoder, this double free is impossible to trigger
    from Python. This issue has been resolved in version 5.4.0 and all users should upgrade to UltraJSON
    5.4.0. There are no known workarounds for this issue. (CVE-2022-31117)

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