Hewlett-Packard Data Protector DtbClsLogin Utf8cpy Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett-Packard Data Protector. Authentication is not required to exploit this vulnerability. The specific flaw exists within the function DtbClsLogin defined in the module dpwindtb.dll on Windows and libdplindtb.so on Linux. This function takes user supplied input and copies it directly to a stack buffer. By providing a large enough string this buffer can be overrun and may result in arbitrary code execution dependent on the underlying operating system.
