CVE-2010-2227: Apache Tomcat Remote Denial Of Service and Information
               Disclosure Vulnerability

Severity: Important

Vendor:
The Apache Software Foundation

Versions Affected:
Tomcat 5.5.0 to 5.5.29
Tomcat 6.0.0 to 6.0.27
Tomcat 7.0.0

Note: 7.0.0 is still beta.
Note: The unsupported Tomcat 3.x, 4.x and 5.0.x versions may also be
affected.

Description:
Several flaws in the handling of the 'Transfer-Encoding' header were
found that prevented the recycling of a buffer. A remote attacker could
trigger this flaw which would cause subsequent requests to fail and/or
information to leak between requests.

Mitigation:
- - Tomcat 5.5.x users should upgrade to 5.5.30 or apply this patch:
  http://svn.apache.org/viewvc?view=revision&revision=959428
- - Tomcat 6.0.x users should upgrade to 6.0.28 or apply this patch:
  http://svn.apache.org/viewvc?view=revision&revision=958977
- - Tomcat 7.0.x users should upgrade to 7.0.1 when released or apply this
patch:
  http://svn.apache.org/viewvc?view=revision&revision=958911

- - All users may mitigate this flaw by running Tomcat behind a reverse
proxy (such as Apache httpd 2.2) that rejects invalid values for
Transfer-Encoding.
