(RHSA-2013:0872) Important: tomcat5 and tomcat6 security update

Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.

A flaw was found in the way the tomcat5 and tomcat6 init scripts handled
the tomcat5-initd.log and tomcat6-initd.log log files. A malicious web
application deployed on Tomcat could use this flaw to perform a symbolic
link attack to change the ownership of an arbitrary system file to that of
the tomcat user, allowing them to escalate their privileges to root.
(CVE-2013-1976)

Note: With this update, tomcat5-initd.log and tomcat6-initd.log have been
moved to the /var/log/ directory.

Red Hat would like to thank Simon Fayer of Imperial College London for
reporting this issue.

Warning: Before applying the update, back up your existing JBoss Enterprise
Web Server installation (including all applications and configuration
files).

Users of Tomcat should upgrade to these updated packages, which resolve
this issue. Tomcat must be restarted for this update to take effect.
