RHEL 6 : tomcat6 (RHSA-2013:0869)

critical Nessus Plugin ID 66660

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for tomcat6.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:0869 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL tomcat6 package based on the guidance in RHSA-2013:0869.
