-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Hewlett-Packard OpenView Network Node
Manager. Authentication is not required to exploit this vulnerability.
The exploit would require a crafted HTTP request to the target host.

The specific flaw exists within the ovutil.dll module which is loaded by
the ovwebsnmpsrv.exe process which in turn can be reached remotely
through the jovgraph.exe CGI program. By supplying overly large values
to variables passed through an HTTP request a sscanf can be made to
overflow a static buffer. An attacker can leverage this to execute
arbitrary code under the context of the user running the webserver.

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