A single bit is wrong in this file, I'd blame that on random corruption.

corruption during download ? can't the updater do some checksum on the downloaded file to check that it is the good one and redownload if failed ? (assuming server side checksum have already been done on deployement and can be provided to the updater when needed).

I don't think it could have happened during download or the previous updates would have triggered the error already. Might be a memory or storage error.
