The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6629-3 advisory.

  - 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.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6629-1 advisory.

  - UltraJSON (aka ujson) through 5.1.0 has a stack-based buffer overflow in Buffer_AppendIndentUnchecked     (called from encode). Exploitation can, for example, use a large amount of indentation. (CVE-2021-45958)
