"The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2022-8197 advisory.

  - In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres
    database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to
    free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of
    service. (CVE-2022-31625)

  - In PHP versions 7.4.x below 7.4.28, 8.0.x below 8.0.16, and 8.1.x below 8.1.3, when using filter functions
    with FILTER_VALIDATE_FLOAT filter and min/max limits, if the filter fails, there is a possibility to
    trigger use of allocated memory after free, which can result it crashes, and potentially in overwrite of
    other memory chunks and RCE. This issue affects: code that uses FILTER_VALIDATE_FLOAT with min/max limits.
    (CVE-2021-21708)

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