GLSA 200703-16: Apache JK Tomcat Connector: Remote execution of arbitrary code

http://security.gentoo.org/

Severity:	high
Title:	Apache JK Tomcat Connector: Remote execution of arbitrary code
Date:	03/16/2007
Bugs:	#169433
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	Architecture(s)
www-apache/mod_jk	< 1.2.21-r1	>= 1.2.21-r1	All supported architectures

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"
