Description

It was discovered that EAP packages in certain versions of Red Hat Enterprise Linux use incorrect permissions for /etc/sysconfig/jbossas configuration files. The file is writable to jboss group (root:jboss, 664). On systems using classic /etc/init.d init scripts (i.e. on Red Hat Enterprise Linux 6 and earlier), the file is sourced by the jboss init script and its content executed with root privileges when jboss service is started, stopped, or restarted.

Affected products

Red Hat JBoss EAP: 6.0.0, 6.4.0, 5.0.0
