Vulnerability: Apache Tomcat packaging on RedHat-based distros

CVE-2016-5425

Discovered by:
Dawid Golunski (http://legalhackers.com)

Affected systems: Multiple Tomcat packages on RedHat-based systems
including: CentOS,Fedora,OracleLinux,RedHat etc.

Short Description:

Apache Tomcat packages provided by default repositories of RedHat-based
distributions (including CentOS, RedHat, OracleLinux, Fedora,  etc.)
create a tmpfiles.d configuration file with insecure permissions which
allow attackers who are able to write files with tomcat user permissions
(for example, through a vulnerability in web application hosted on Tomcat)
to escalate their privileges from tomcat user to root and fully compromise
the target system.
