Scientific Linux Security Update : tomcat6 on SL6.x (noarch) (20130528)

medium Nessus Plugin ID 66665

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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 SLSA-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)

Tomcat must be restarted for this update to take effect.

Solution

Update the affected packages.
