The NSS library library before 3.12.3, as used in Firefox; GnuTLS
before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other
products support MD2 with X.509 certificates, which might allow
remote attackers to spooof certificates by using MD2 design flaws
to generate a hash collision in less than brute-force time. NOTE:
the scope of this issue is currently limited because the amount of
computation required is still large (CVE-2009-2409).
This update provides a solution to these vulnerabilities.

Description:
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
