DataDirect OpenAccess oaagent.exe GIOP Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of DataDirect SequeLink. Authentication is not required to exploit this vulnerability. The specific flaw exists within how the application parses a packet that is received. When parsing a field in this packet, the application will use a signed length to copy data into a statically sized buffer located on the heap. This can lead to a heap-based buffer overflow and allows for code execution under the context of the service.
