"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2022:0847-1 advisory.

  - 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 this issue but has instead relied only on the application's self-reported version
number.");
