Rocky Linux 8 administrators can install new security errata covering rrdtool, Thunderbird, PHP 7.4, container-tools, Ruby 2.5 and 3.3, and MariaDB 10.11. Most advisories carry an Important severity rating, with the PHP 7.4 release addressing vulnerabilities across module.libzip, php-pear, and php-pecl-xdebug, while the container-tools update patches podman, buildah, and skopeo alongside bug fixes and enhancements. The Ruby updates resolve security issues in rubygem-abrt, rubygem-bundler, and rubygem-pg components, and the MariaDB advisory fixes flaws in Judy and galera packages.
