leveldb Team 068d5ee1a3 leveldb: Check slice length in Footer::DecodeFrom() Without this check decoding the footer in Table::Open() can read uninitialized bytes from a buffer allocated on the stack if the file was unexpectedly short. In practice this is probably fine since this function validates a magic number but MSan complains about branching on uninitialized data. PiperOrigin-RevId: 525271012		pirms 2 gadiem
