[原文]Tomcat before 5.0.27-r3 in Gentoo Linux sets the default permissions on the init scripts as tomcat:tomcat, but executes the scripts with root privileges, which could allow local users in the tomcat group to execute arbitrary commands as root by modifying the scripts.

[CNNVD]Gentoo Linux Tomcat Ebuild不安全安装权限漏洞(CNNVD-200412-772)

        Gentoo Linux下的Tomcat 5.0.27-r3之前的版本将初始化脚本默认权限设为tomcat:tomcat,但使用根权限执行该脚本,tomcat组群下的本地用户可以利用该漏洞像根用户样修改脚本执行任意命令。
