The remote Red Hat host is missing one or more security updates.
Updated tomcat6 packages that fix two security issues are now
available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
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
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.
