DESCRIPTION:
Mati Aharoni has discovered a vulnerability in HP OpenView Network
Node Manager, which can be exploited by malicious people to
compromise a vulnerable system.

The vulnerability is caused due to a boundary error within
ovwparser.dll, which can be exploited to cause a stack-based buffer
overflow via an overly long HTTP GET request to ovas.exe on default
port 7510/TCP.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 7.51. Other versions may
also be affected.

SOLUTION:
Restrict network access to ovas.exe.
