1) Introduction
===============

Symantec's Norton AntiVirus? 2004 Professional is the world?s most trusted
antivirus solution with advanced protection. It protects email, instant
messages,
and other files by removing viruses automatically. Expanded threat detection
alerts
the user to spyware and similar hacking programs. It also supplies advanced
tools for
data recovery and secure file deletion and a license for two computers.

2) Bug
======

Symantec Norton AntiVirus 2004 installs many DLLs(Dynamic Link Library)
and COM(Component Object Model) objects. One of its DLL's "ccErrDsp.dll"
Which is by the default installation options located at :
C:\Program Files\Common Files\Symantec Shared\ccErrDsp.dll

"ccErrDsp.dll" registers "CcErrDsp.ErrorDisplay.1"  COM Object.
After Symantec Norton AntiVirus 2004 was used, this object can be created
Localy & Remotely!

For Example:
Set symkiller = CreateObject("CcErrDsp.ErrorDisplay.1" )

The vulnerability appears in the "sProduct" parameter at the "DisplayError"
function of the object.
The "DisplayError" recieves the following parameters:
DisplayError(
                        [in] long nParentWnd,
                        [in] int nModuleId,
                        [in] int nErrorId,
                        [in] BSTR sCaption,
                        [in] BSTR sErrorText,
                        [in] BSTR sProduct,
                        [in] BSTR sVersion,
                        [in, optional] VARIANT varKeyArray,
                        [in, optional] VARIANT varValueArray,
                        [out, retval] VARIANT_BOOL* pRet);

Which means that the following assignment:
object.DisplayError(1,1,1,[STR <=255],[STR <=255],[Really Long String -
'A'>521950],[STR <=255]);
Will cause a Stack Buffer Overflow, which does not allow code execution.
