I was recently notified that my installation of php is vulnerable and needs updating. I am running SLES 12 SP5 and using php-7.2.5. I wanted to update to a newer version but the repositories don't have the packages needed. I also tried removing php-7.2.5 and installing php-7.4.6. But, I need the php74-memcached module which is unavailable. How can upgrade php to be in compliance with my security team?
