DESCRIPTION:
Alex Wheeler has reported some vulnerabilities in ZENworks products,
which can be exploited by malicious people to compromise a vulnerable
system.

The vulnerabilities are caused due to some integer overflows and
boundary errors in the Remote Management authentication protocol
handling in zenrem32.exe. These can be exploited to cause heap-based
and stack-based buffer overflows by sending some specially crafted
traffic.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities affect the following versions:
* Novell ZENworks 6.5 Desktop Management
* Novell ZENworks 6.5 Server Management
* Novell ZENworks for Desktops 4.x
* Novell ZENworks for Servers 3.x

SOLUTION:
Restrict access to the Remote Management authentication service.
