Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of Novell File Reporter Engine. Authentication is not 
required to exploit this vulnerability.

The specific flaw exists within NFREngine.exe which communicates with the Agent 
component over HTTPS on TCP port 3035. When parsing tags inside the <RECORD> 
element, the application lacks a size check before pushing strings to a memcpy. 
An attacker can leverage this to corrupt the thread's stack. This vulnerability 
can result in remote code execution under the context of the SYSTEM account.
