[Podofo-users] stack-overflow in Podofo[0.9.7]

[默契 <bi...@gm...>]

Hi guy ，I found a stack overflow in podofoxmp

It looks like an infinite recursion。
After analyzing the source code, I found that this was due to the following
reasons
-----------------------------------------------------------------------------------------
EPdfDataType PdfTokenizer::DetermineDataType
{
else if( pszToken[0] == '[' )
            return ePdfDataType_Array;
}

PdfTokenizer::ReadDataType
{
case ePdfDataType_Array:
            this->ReadArray( rVariant, pEncrypt );
}

PdfTokenizer::ReadArray
{
if( eType == ePdfTokenType_Delimiter && pszToken[0] == ']' ) //compare the
"]" symbol here
            break;
 this->GetNextVariant( pszToken, eType, var, pEncrypt );
}

PdfTokenizer::GetNextVariant
{
 EPdfDataType eDataType = this->DetermineDataType( pszToken, eType,
rVariant );
}
--------------------------------------------------------------------------------------------
If you don't have "]", you go into recursion

Like this！！！

the trigger sample is shown below, run the following command:
./podofoxmp id^%000000,sig^%11,src^%002118,time^%20356746,op^%havoc,rep^%32
