-- Affected Vendors:
Novell

-- Affected Products:

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell ZENWorks. Authentication is not
required to exploit this vulnerability.

The specific flaw exists within the ZenRem32.exe process which listens
by default on TCP and UDP ports 1761. When processing the Console DN
field of incoming requests, the process can be made to overflow a stack
buffer by 2 bytes. Due to the location of the destination buffer, an
attacker can abuse this to overwrite a portion of a return address and
execute remote code under the context of the SYSTEM user.

-- Vendor Response:
Novell states:
Fixed in ZENworks 7 Desktop Management Support Pack 1 Interim Release 4
Hot Patch 5:
