LibreSSL not affected by DROWN attack

Contributed by phessler on from the super-duper-tuesday dept.

As noted by Bernard Spil, the OpenSSL bugs disclosed on 2016-03-01 have very little impact on LibreSSL, especially on OpenBSD. However, we will briefly mention the two high-profile issues:

  • LibreSSL (on any platform) is not affected by DROWN. Support for SSLv2 was flensed out quite a while ago.
  • Cachebleed is local-only, and requires a lot effort to get. This is thought to be very difficult to exploit on OpenBSD due to many of the normal mitigations on an OpenBSD system. Other systems without such mitigations may not be so lucky.

      Does that mean we will still get a patch for the "Cachebleed", even if it is only a local vulnerability?

        It is being looked at, but cannot be rushed as a mistake in fixing this could result in a much bigger problem.

        Read the FAQ ( especially Q5.

          Publish a anonymous message makes one a coward in this community? I think what is really coward is to do it with a fake name. It has been probed that the anonymity is more good synonymous with humility; and humility is condition, in my opinion, without which no one can be honest.

      You know the bugs get serious when they are given names which have to do with misadventure, death, serious injury, fluffy animals, or a combination of such items.
