Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

An error in the Apache Tomcat JK Connector might allow for an
information disclosure flaw.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

The Apache Tomcat JK Connector (aka mod_jk) connects the Tomcat
application server with the Apache HTTP Server.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  www-apache/mod_jk      < 1.2.27                         >=3D 1.2.27

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

The Red Hat Security Response Team discovered that mod_jk does not
properly handle (1) requests setting the "Content-Length" header while
not providing data and (2) clients sending repeated requests very
quickly.

Impact
=3D=3D=3D=3D=3D=3D

A remote attacker could send specially crafted requests or a large
number of requests at a time, possibly resulting in the disclosure of a
response intended for another client.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Apache Tomcat JK Connector users should upgrade to the latest
version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=3Dwww-apache/mod_jk-1.2.27"
