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.


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.


iDefense has confirmed the existence of this vulnerability in version 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.


iDefense is unaware of an effective workarounds for this issue.


Novell's ZENworks team has addressed this vulnerability within ZENworks 7
Asset Management SP1 IR11.  More information can be found by visiting .
