TITLE:
Apache Tomcat JK Web Server Connector Information Disclosure

SECUNIA ADVISORY ID:
SA34621

VERIFY ADVISORY:
http://secunia.com/advisories/34621/

DESCRIPTION:
A vulnerability has been reported in the Apache Tomcat JK Web Server
Connector, which can be exploited by malicious people to disclose
sensitive information.

The vulnerability is caused due to an error when handling empty POST
requests with a non-zero "Content-Length" header. This can be
exploited to disclose response data associated with the request of a
different user via specially crafted HTTP requests.

The vulnerability is reported in versions 1.2.0 through 1.2.26.
Tomcat versions 4.0.0 through 4.0.6, 4.1.0 through 4.1.36, 5.0.0
through 5.0.30, and 5.5.0 through 5.5.27 are reportedly also affected
as they contain the vulnerable connector version in their source
packages.

SOLUTION:
Update to version 1.2.27 or later.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Red Hat Security Response Team.
