Descriptions
The Tomcat package on Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux, and possibly other Linux distributions uses weak permissions for /usr/lib/tmpfiles.d/tomcat.conf, which allows local users to gain root privileges by leveraging membership in the tomcat group.
El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux y posiblemente en otros productos distribuidos por Linux utiliza permisos débiles para /usr/lib/tmpfiles.d/tomcat.conf, lo que permite a usuarios locales obtener privilegios de root aprovechando su pertenencia al grupo tomcat.
It was discovered that the Tomcat packages installed configuration file /usr/lib/tmpfiles.d/tomcat.conf writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges.
