ID: 200703-16

Synopsis
========
The Apache Tomcat Connector (mod_jk) contains a buffer overflow
vulnerability that could result in the remote execution of arbitrary
code.
Background
==========
The Apache HTTP server is a very widely used web server. mod_jk
provides the JK module for connecting Tomcat and Apache using the ajp13
protocol.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apache/mod_jk < 1.2.21-r1 >= 1.2.21-r1
Description
===========
ZDI reported an unsafe memory copy in mod_jk that was discovered by an
anonymous researcher in the map_uri_to_worker function of
native/common/jk_uri_worker_map.c .
Impact
======
A remote attacker can send a long URL request to an Apache server using
Tomcat. That can trigger the vulnerability and lead to a stack-based
buffer overflow, which could result in the execution of arbitrary code
with the permissions of the Apache user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Apache Tomcat users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_jk-1.2.21-r1"
