(RHSA-2013:0869) Important: 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 tomcat6 init script handled the
tomcat6-initd.log 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, tomcat6-initd.log has been moved from
/var/log/tomcat6/ to the /var/log/ directory.

It was found that the RHSA-2013:0623 update did not correctly fix
CVE-2012-5887, a weakness in the Tomcat DIGEST authentication
implementation. A remote attacker could use this flaw to perform replay
attacks in some circumstances. Additionally, this problem also prevented
users from being able to authenticate using DIGEST authentication.
(CVE-2013-2051)

Red Hat would like to thank Simon Fayer of Imperial College London for
reporting the CVE-2013-1976 issue.

Users of Tomcat are advised to upgrade to these updated packages, which
correct these issues. Tomcat must be restarted for this update to take
effect.
