    Summary: Updated php packages fix security vulnerability

    Details: Updated php packages fix security vulnerability: In PHP versions 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). The php packages have been updated to 8.0.12 that fixes this issue and other bugs.
