Thanks for reporting. I pinged upstream pointing him at the report, I hope he gets back to me quickly. It can surely be used to fill up disk space on a DoS attack. I don't know anything about Ocaml's serialisations methods so I can't say if this could be exploited to cause a buffer overflow. In the meantime, the problem seems to be in io.ml, line 65: Unix.chmod tmp 0o666; I've asked upstream if he can see any problems in just removing that line.
