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

The specific flaw resides in the web console running on TCP ports 8028
and 8030. The server exposes a web interface and accepts SOAP
connections. While parsing the Content-Length header within a SOAP
request an integer overflow can occur. This integer overflow triggers a
subsequent overflow during a memory copy operation leading to arbitrary
code execution under the context of the SYSTEM user.

-- Vendor Response:
Novell has issued an update to correct this vulnerability. More
