Thanks to Yuval Yarom and Naomi Benger for discovering this
flaw and to Yuval Yarom for supplying a fix.

Thanks for mancha for backporting the fix to OpenSSL 0.9.8 branch.

ff7b021040 Fix overly lenient comparisons: 
- EC_GROUP_cmp shouldn't consider curves equal just because
      the curve name is the same. (They really *should* be the same
      in this case, but there's an EC_GROUP_set_curve_name API,
      which could be misused.)

    - EC_POINT_cmp shouldn't return 0 for ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED
      or EC_R_INCOMPATIBLE_OBJECTS errors because in a cmp API, 0 indicates
      equality (not an error).
