Apache Tomcat JK Connector: Information disclosure — GLSA 200906-04

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

Affected packages

Package	www-apache/mod_jk on all architectures
Affected versions	< 1.2.27
Unaffected versions	>= 1.2.27

Background

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

Description

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

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

There is no known workaround at this time.

Resolution

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

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