Effect Spore is an ability in Polished Crystal that has a 30% chance of inflicting a status condition (Sleep, Paralysis, or Poison) on an opponent that makes contact with the user. You can find this ability on a handful of Grass and Bug type Pokémon including the Vileplume, Bulbasaur, and Paras evolutionary line.
Burn nor Freeze are not possible status conditions inflicted by Effect Spore.
