Security Fix

CVE-2013-1976
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.
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.

Security Fixes

CVE-2012-3546
It was found that when an application used FORM authentication, along with another component that calls request.setUserPrincipal() before the call to FormAuthenticator#authenticate() (such as the Single-Sign-On valve), it was possible to bypass the security constraint checks in the FORM authenticator by appending "/j_security_check" to the end of a URL. A remote attacker with an authenticated session on an affected application could use this flaw to circumvent authorization controls, and thereby access resources not permitted by the roles associated with their authenticated session.
CVE-2012-5885, CVE-2012-5886, CVE-2012-5887
Multiple weaknesses were found in the Tomcat DIGEST authentication implementation, effectively reducing the security normally provided by DIGEST authentication. A remote attacker could use these flaws to perform replay attacks in some circumstances.
Users of Tomcat should upgrade to these updated packages, which correct these issues. Tomcat must be restarted for this update to take effect.
