Currently libzerocoin ignores the transaction meta data that is supposed to be added to the Signature of Knowledge. This leaves zerocoin spend transactions susceptible to middle man/malleability attacks.
Adding the transaction hash to the SoK hash that the SoK challenge is based on should help prevent malleability.
