Novell ZENworks Asset Management Collection Client Heap Overflow Vulnerability

iDefense Security Advisory 12.01.06
http://labs.idefense.com/intelligence/vulnerabilities/
Dec 01, 2006

I. BACKGROUND

Novell Inc's ZENworks is a set of tools used to automate IT management and business processes across the various computing resources
within an organization.

The Collection Client provides functionality, as a service, that will supply the Collection Server with information regarding the
managed machine's hardware and software configuration.

For more information, visit http://www.novell.com/products/zenworks/

II. DESCRIPTION

Remote exploitation of an integer overflow vulnerability in Novell Inc.'s ZENworks Asset Management could potentially allow an
attacker to execute arbitrary code with SYSTEM privileges on Windows or root on the various supported UNIX based operating systems.

A heap overflow may occur when processing specially crafted packets sent to the Collection Client daemon. The root cause of this
vulnerability is identical to that of the vulnerability in Msg.dll. For more information please consult the Msg.dll advisory.

III. ANALYSIS

Successful exploitation of this vulnerability could allow a remote attacker to take complete control of the affected system.

While researching this vulnerability, iDefense Labs found that the Task Server and Collection Server components were also affected.
It seems that the Collection Client is statically linked with the Msg.dll library.

IV. DETECTION

iDefense has confirmed the existence of this vulnerability in version
7.0.0.36 of the CClient.exe and Msg.dll files included with Novell Inc's ZENworks Asset Management 7.0 SP1. Older versions are
suspected to be vulnerable as well.

V. WORKAROUND

iDefense is unaware of an effective workarounds for this issue.

VI. VENDOR RESPONSE
