FreeBSD : tomcat -- Denial of Service (7f5ccb1d-439b-11e1-bc16-0023ae8e59f0)

medium Nessus Plugin ID 57629

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Tomcat security team reports :

Analysis of the recent hash collision vulnerability identified unrelated inefficiencies with Apache Tomcat's handling of large numbers of parameters and parameter values. These inefficiencies could allow an attacker, via a specially crafted request, to cause large amounts of CPU to be used which in turn could create a denial of service. The issue was addressed by modifying the Tomcat parameter handling code to efficiently process large numbers of parameters and parameter values.

Solution

Update the affected packages.
