Module.get_symbol_from_list: local variable 'SymbolStartName' referenced before assignment about winappdbg HOT 5 CLOSED

Yes, I did some debugging as well, it's trying to find the "tightest" symbol encompassing the address. None seems to be the correct return value in the case of no match, yes. So far so good. The 2 functions of the contribution both look for the "closest" match. The first one considers the symbols' size. If no match is found, the second function ignores the size and just looks for the nearest symbol starting address and takes that. The bug is that if there are no symbols at all in the module, the said error is thrown.

quick fix for everyone until an offical fix

    def get_symbol_from_list(self,address):
        found = None
        SymList = {}
        SortedSymList = {}
        f = False
        for (SymbolName, SymbolAddress, SymbolSize) in self.iter_symbols():
            SymList[SymbolAddress] = SymbolName
        SortedSymList = sorted(SymList.items())
        for SymbolAddress,SymbolName in SortedSymList:
            if SymbolAddress <= address:
                f = True 
                SymbolStartAddress = SymbolAddress
                SymbolStartName = SymbolName
            else:
                break
        if f:
            found = (SymbolStartName, SymbolStartAddress, 0)
        return found

The function came from this pull request, this may give a hint to why it's failing: 01d7218

I believe the function should be returning None when the symbol is not found.

Maybe @hardik05 could provide additional info?

i was facing some issue with previous function, so i added def get_symbol_from_list
this function basically parses symbol file and saves there address and name in a list. then when winappdbg request for a symbol at a address, it first tries the default function -> get_symbol_at_address if its not able to find then it calls get_symbol_from_list.
you can check if symbol file is proper or symbols are there?
lastly you can modify the function to check for None and handle them accordingly.
