Code Execution Vulnerability

Operations Agent for NonStop

Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of HP Operations Agent for NonStop Server. User 
interaction is required to exploit this vulnerability in that the target must 
check the status of an existing node on the network.

The specific flaw exists within ELinkService process which listens on TCP 
ports 7771 and 8976 by default. The process performs insufficient bounds 
checking on user-supplied data within in a HEALTH packet prior to copying it 
into a fixed-length buffer on the stack. Remote, unauthenticated attackers can 
exploit this vulnerability by sending malformed message packets to the target, 
which could ultimately lead to arbitrary code execution under the context of 
the SYSTEM user.

Vendor Response
Hewlett-Packard states:

This vulnerability is being disclosed publicly without a patch in accordance
