CentOS Errata and Security Advisory CESA-2013:0870
Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.
A flaw was found in the way the tomcat5 init script handled the
catalina.out log file. 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, /var/log/tomcat5/catalina.out has been moved to the
/var/log/tomcat5-initd.log file.
Red Hat would like to thank Simon Fayer of Imperial College London for
reporting this issue.
Users of Tomcat are advised to upgrade to these updated packages, which
correct this issue. Tomcat must be restarted for this update to take
effect.
