[reSIProcate] memory overrun in MsgHeaderScanner.cxx

[kaiduan xie <kaiduanx@xxxxxxxx>]

Hi, all,

Just found a memory overrun in MsgHeaderScanner.cxx, 

    static CharInfo charInfoArray[UCHAR_MAX];
    
    static void initCharInfoArray()
    {
        for(unsigned int charIndex = 0; charIndex <=
UCHAR_MAX; ++charIndex) 
        {
            charInfoArray[charIndex].category =
ccOther;
            charInfoArray[charIndex].textPropBitMask =
0;
        }

Here, charInfoArray has a size of UCHAR_MAX, but the
charIndex has value of UCHAR_MAX. Should we change it
to static CharInfo charInfoArray[UCHAR_MAX + 1];

Please confirm that.

Many thanks,

kaiduan
