Topic created on: February 27, 2011 09:13 CST by GTALovesItDotCom .

I am trying to do a binary diff of recent patch CVE-2011-0027. I am using TurboDiff and IDA free (4.9) and it gives an access violation when loading msado15.ana for the newly patched dll ... I was wondering if anyone can give it a shot using the free or pro IDA and turbo diff.

Or know of a better tool (that is free)

When I'm comparing differences in binaries (and i can't use Zynamix's BinDiff), I usually just use WinHex and IDA/PEFile together. If you open up WinHex, open the two files the fiel compare utility (I think you go to File Manager and then Compare). Depending on if you're searching for the differences or similarities, WinHex will generate a text file with the offsets of each difference (or offsets where the bytes are identical). You can then use PEFile and IDA to ascertain whether the difference is an assembly instruction or PE file header field.
