The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 21.04 / 21.10 host has packages installed that are affected by a vulnerability as referenced in the USN-5125-1 advisory.

  - In PHP versions 7.3.x up to and including 7.3.31, 7.4.x below 7.4.25 and 8.0.x below 8.0.12, when running     PHP FPM SAPI with main FPM daemon process running as root and child worker processes running as lower-     privileged users, it is possible for the child processes to access memory shared with the main process and     write to it, modifying it in a way that would cause the root process to conduct invalid memory reads and     writes, which can be used to escalate privileges from local unprivileged user to the root user.
    (CVE-2021-21703)
